The first is a 2 process warrior that uses a forward imp in combination with a backwards djn_strean. It would benefit greatly from some DAT padding in front but I didn't give the GA any way to do that. The second (weaker) one has more processes and uses an imp carpet (I don't know what else to call it) which it copies into memory moving backwards until it overwrites itself and starts executing the MOVs. (Assuming it beats the djn_stream, ...or.. wait, the djn stream wouldn't hurt it-they're kind of hard to read.)

The current pmars simulator, 0.9.2, is available at http://sourceforge.net/projects/corewar/ My preference is the X11 version on linux. [Choose whether you want the console or X11 version at build time]. On Windows the graphical version, pmarsv, isn't really a Windows app. but will run in a window. Better is to run it full-screen. If you have a fast processor you mightn't be able to slow it down enough to see whats going on. An alternative, true GUI version for linux [actually GTK+] is available from http://corewars.sourceforge.net/ [there's a download link top-right corner]. Take care - it supports both '94 standard REDCODE [excluding pmars extensions like pspace] and it's own language "corewars" which is little used/supported [and confusingly named]. The pmars[v] version is the standard and much better suited to code-development [e.g. it shows more useful inforamtion and includes a full debugger] but some may find the "corewars" version prettier and easier to control speedwise [one can control the number of steps per execution block plus the speed of each execution block via the Option/Display screen]. The Game Statistic window can also be interesting to watch during a run. The default scoring differs from pmars but can be configured. The pmars team are also working on jmars, a java version, but last I looked it could with a front-end. [and would love your help no doubt]. An alternative for your purposes may be to access the http://corewars.sourceforge.net site directly as it allows one to select and run published warriors in a simple java applet. [note "simple"] Re visually exciting - some warriors look good / interesting / are instructive when running e.g. rave, bluefunk, carbonite are easy to explain. For a visually exciting battle I suggest a stun-bomber vs imp-stone [e.g. bluefunk] - if you have a situation where the stone is stunned & killed the imp revival can be quite dramatic.

Is > there a pMARS simulator more recent than 0.8.6? Lukasz already mentioned the 0.9.2 source available from sourceforge. The difference to 0.8.6 is mainly in packaging rather than any new features. So, the answer is no I guess. > Has anyone done an x86/Windows GUI version? Linux/GNOME? If > not, would there be any interest in such a thing? No, no, and yes! Or rather, there are a few binaries that run on Windows here: www.koth.org/pmars but they aren't what I'd call modern GUI programs. > I was hoping to do a Core Wars demo for an upcoming > high-tech expo (the more visually exciting the better). The GUI's are rather primitive and to the non-initiated the core display is sadly uninteresting (Cool! Flashing lights! Yeah right.). There are a few 'warriors' that produce visual effects (fireworks, game of life) on the display by reading/writing/executing core cells. Most were produced as entries in a tournament held by Anton Marsden, and their source should be here: http://pauillac.inria.fr/~doligez/corewar/Anton'sTournamentRnd3.txt but unfortunately I can't confirm that at the moment. At the bottom is my own attempt at producing some visual effects on a core display (tested on Win95 pmarsv and X11 pmars). Be sure to read the configuration section before running it. Not exactly what you were looking for, I'm afraid.

Is > there a pMARS simulator more recent than 0.8.6? Lukasz already mentioned the 0.9.2 source available from sourceforge. The difference to 0.8.6 is mainly in packaging rather than any new features. So, the answer is no I guess. > Has anyone done an x86/Windows GUI version? Linux/GNOME? If > not, would there be any interest in such a thing? No, no, and yes! Or rather, there are a few binaries that run on Windows here: www.koth.org/pmars but they aren't what I'd call modern GUI programs. > I was hoping to do a Core Wars demo for an upcoming > high-tech expo (the more visually exciting the better). The GUI's are rather primitive and to the non-initiated the core display is sadly uninteresting (Cool! Flashing lights! Yeah right.). There are a few 'warriors' that produce visual effects (fireworks, game of life) on the display by reading/writing/executing core cells. Most were produced as entries in a tournament held by Anton Marsden, and their source should be here: http://pauillac.inria.fr/~doligez/corewar/Anton'sTournamentRnd3.txt but unfortunately I can't confirm that at the moment. At the bottom is my own attempt at producing some visual effects on a core display (tested on Win95 pmarsv and X11 pmars). Be sure to read the configuration section before running it.

I'm not convinced that making logic (or, more to the point, scanning loops) faster/smaller would have a great impact on the game. Sure, a 2c scanner would be cool, and it might even wipe the floor with all the old stuff. Consider: you have an instruction 'scan' that embodies a scan loop at 2c, or whatever. That is, it falls through to the next instruction only when it finds something. You're still going to have an awful lot of code to deal with the results of your find. Anyway, what I wanted to say was that IMO one reason complex decision making warriors don't thrive is that it's much more difficult to build in redundancy than with the 'dumber' components. Airbags went a long way in accomplishing this, certainly, but in the end they are more of an escape latch compared to multi-part warriors. The only multi-part scanners I can think of off-hand are Kline's Harmony II, and to a limited extent the multishots by Moore. This has a lot to do with process scheduling, in that anything with many (~100) of processes will have a hard time doing anything more fancy than executing simple loops -- certainly no complex if-then's or do-until's.

What does (expression or term of your choice) mean? 23. Other questions? ------------------------------------------------------------------------ 1. What is Core War? Core War is a game played by two or more programs (and vicariously by their authors) written in an assembly language called Redcode and run in a virtual computer called MARS (for Memory Array Redcode Simulator). The object of the game is to cause all processes of the opposing program to terminate, leaving your program in sole posession of the machine. There are Core War systems available for most computer platforms. Redcode has been standardised by the ICWS, and is therefore transportable between all standard Core War systems. The system in which the programs run is quite simple. The core (the memory of the simulated computer) is a continuous array of instructions, empty except for the competing programs. The core wraps around, so that after the last instruction comes the first one again. There are no absolute addresses in Core War. That is, the address 0 doesn't mean the first instruction in the memory, but the instruction that contains the address 0. The next instruction is 1, and the previous one obviously -1. However, all numbers are treated as positive, and are in the range 0 to CORESIZE-1 where CORESIZE is the amount of memory locations in the core - this means that -1 would be treated as CORESIZE-1 in any arithmetic operations, eg. 3218 + 7856 = (3218 + 7856) mod CORESIZE. Many people get confused by this, and it is particularly important when using the SLT instruction. Note that the source code of a program can still contain negative numbers, but if you start using instructions like DIV #-2, #5 it is important to know what effect they will have when executed. The basic unit of memory in Core War is one instruction. Each Redcode instruction contains three parts: * the opcode * the source address (a.k.a. the A-field) * the destination address (a.k.a. the B-field) The execution of the programs is equally simple. The MARS executes one instruction at a time, and then proceeds to the next one in the memory, unless the instruction explicitly tells it to jump to another address. If there is more than one program running, (as is usual) the programs execute alternately, one instruction at a time. The execution of each instruction takes the same time, one cycle, whether it is MOV, DIV or even DAT (which kills the process). Each program may have several processes running. These processes are stored in a task queue. When it is the program's turn to execute an instruction it dequeues a process and executes the corresponding instruction. Processes that are not killed during the execution of the instruction are put back into the task queue. Processes created by a SPL instruction are added to the task queue after the creating process is put back into the task queue. [ToC] ------------------------------------------------------------------------ 2. Is it "Core War" or "Core Wars"? Both terms are used. Early references were to Core War. Later references seem to use Core Wars. I prefer "Core War" to refer to the game in general, "core wars" to refer to more than one specific battle. [ToC] ------------------------------------------------------------------------ 3. Where can I find more information about Core War? Core War was first described in the Core War Guidelines of March, 1984 by D. G. Jones and A. K. Dewdney of the Department of Computer Science at The University of Western Ontario (Canada). Dewdney wrote several "Computer Recreations" articles in Scientific American which discussed Core War, starting with the May 1984 article. Those articles are contained in two anthologies: Library of Author Title Published ISBN Congress Call Number The Armchair Dewdney, Universe: An New York: W. QA76.6 .D517 A. K. Exploration of H. Freeman �0-7167-1939-8 1988 Computer Worlds 1988 The Magic 0-7167-2125-2 Dewdney, Machine: A New York: W.(Hardcover), QA76.6 A. K. Handbook of H. Freeman �0-7167-2144-9 .D5173 1990 Computer Sorcery 1990 (Paperback) A.K. Dewdney's articles are still the most readable introduction to Core War, even though the Redcode dialect described in there is no longer current. For those who are interested, Dewdney has a home page at http://www.csd.uwo.ca/faculty/akd/. [ToC] ------------------------------------------------------------------------ 4. Core War has changed since Dewdney's articles. Where do I get a copy of the current instruction set? A draft of the official standard (ICWS'88) is available as ftp://www.koth.org/corewar/documents/standards/redcode-icws-88.Z. This document is formatted awkwardly and contains ambiguous statements. For a more approachable intro to Redcode, take a look at Mark Durham's tutorials, ftp://www.koth.org/corewar/documents/tutorial.1.Z and ftp://www.koth.org/corewar/documents/tutorial.2.Z. Steven Morrell has prepared a more practically oriented Redcode tutorial that discusses different warrior classes with lots of example code. This and various other tutorials can be found at http://www.koth.org/papers.html. Even though ICWS'88 is still the "official" standard, you will find that most people are playing by ICWS'94 draft rules and extensions. [ToC] ------------------------------------------------------------------------ 5. What is ICWS'94? Which simulators support ICWS'94? There is an ongoing discussion about future enhancements to the Redcode language. A proposed new standard, dubbed ICWS'94, is currently being evaluated. A major change is the addition of "instruction modifiers" that allow instructions to modify A-field, B-field or both. Also new is a new addressing modes and unrestricted opcode and addressing mode combination ("no illegal instructions"). ICWS'94 is backwards compatible; i.e. ICWS'88 warriors will run correctly on an ICWS'94 system. Take a look at the ICWS'94 draft at ftp://www.koth.org/corewar/documents/icws94.0202.Z for more information. There is a HTML version of this document available at http://www.koth.org/info/icws94.html. You can try out the new standard by submitting warriors to the '94 hills of the KotH servers. Two corewar systems currently support ICWS'94, pMARS (many platforms) and Redcoder (Mac), both available at ftp://www.koth.org/corewar. Note that Redcoder only supports a subset of ICWS'94. [ToC] ------------------------------------------------------------------------ 6. What is the ICWS? About one year after Core War first appeared in Scientific American, the "International Core War Society" (ICWS) was established. Since that time, the ICWS has been responsible for the creation and maintenance of Core War standards and the running of Core War tournaments. There have been six annual tournaments and two standards (ICWS'86 and ICWS'88). The ICWS is no longer active. [ToC] ------------------------------------------------------------------------ 7. What is Core Warrior? Following in the tradition of the Core War News Letter, Push Off, and The 94 Warrior, Core Warrior is a newsletter about strategies and current standings in Core War. Started in October 1995, back issues of Core Warrior (and the other newsletters) are available at http://para.inria.fr/~doligez/corewar/. There is also a Core Warrior index page at http://www.kendalls.demon.co.uk/pak21/corewar/warrior.html which has a summary of the contents of each issue of Core Warrior. Many of the earlier issues contain useful information for beginners. [ToC] ------------------------------------------------------------------------ 8. Where are the Core War archives? Many documents such as the guidelines and the ICWS standards along with previous tournament Redcode entries and complete Core War systems are available via anonymous ftp from ftp://ftp.csua.berkeley.edu/pub/corewar. Also, most of past rec.games.corewar postings (including Redcode source listings) are archived there. Jon Blow (blojo@csua.berkeley.edu) is the archive administrator. When uploading to /pub/corewar/incoming, ask Jon to move your upload to the appropriate directory and announce it on the net. This site is mirrored at: * http://www.koth.org/corewar/ * ftp://www.koth.org/corewar/ * ftp://ftp.inria.fr/INRIA/Projects/para/doligez/cw/mirror The plain text version of this FAQ is automatically archived by news.answers (but this version is probably out-of-date). [ToC] ------------------------------------------------------------------------ 9. Where can I find a Core War system for . . . ? Core War systems are available via anonymous FTP from www.koth.org in the corewar/systems directory. Currently, there are UNIX, IBM PC-compatible, Macintosh, and Amiga Core War systems available there. It is a good idea to check ftp://www.koth.org/corewar/incoming for program updates first. CAUTION! There are many, many Core War systems available which are NOT ICWS'88 (or even ICWS'86) compatible available at various archive sites other than www.koth.org. Generally, the older the program - the less likely it will be ICWS compatible. If you are looking for an ICWS'94 simulator, get pMARS, which is available for many platforms and can be downloaded from: * ftp://ftp.csua.berkeley.edu/pub/corewar (original site) * ftp://www.koth.org/corewar (koth.org mirror) * ftp://ftp.inria.fr/INRIA/Projects/para/doligez/cw/mirror (Planar mirror) * http://www.nc5.infi.net/~wtnewton/corewar/ (Terry Newton) * ftp://members.aol.com/ofechner/corewar (Fechter) Notes: * If you have trouble running pMARS with a graphical display under Win95 then check out http://www.koth.org/pmars.html which should have a pointer to the latest compilation of pMARS for this environment. * RPMs for the Alpha, PowerPC, Sparc and i386 can be found at ftp://ftp.inria.fr/INRIA/Projects/para/doligez/cw/pmars-rpm/ Reviews of Core War systems would be greatly appreciated in the newsgroup and in the newsletter. Below is a not necessarily complete or up-to-date list of what's available at www.koth.org: MADgic41.lzh corewar for the Amiga, v4.1 MAD4041.lzh older version? MAD50B.lha corewar for the Amiga, beta version 5.0 Redcoder-21.hqx corewar for the Mac, supports ICWS'88 and '94 (without extensions) core-11.hqx corewar for the Mac core-wars-simulator.hqx same as core-11.hqx? corewar_unix_x11.tar.Z corewar for UNIX/X-windows, ICWS'86 but not ICWS'88 compatible koth31.tar.Z corewar for UNIX/X-windows.

Where can I find warrior code? To learn the game, it is a good idea to study previously posted warrior code. The FTP archives have code in the ftp://www.koth.org/corewar/redcode directory. A clearly organized on-line warrior collection is available at the Core War web sites (see below). [ToC] ------------------------------------------------------------------------ 11. I do not have FTP. How do I get all this great stuff? There is an FTP email server at bitftp@pucc.princeton.edu. This address may no longer exist. I haven't tested it yet. Send email with a subject and body text of "help" (without the quotes) for more information on its usage. Note that many FTP email gateways are shutting down due to abuse. To get a current list of FTP email servers, look at the Accessing the Internet by E-mail FAQ posted to news.answers. If you don't have access to Usenet, you can retrieve this FAQ one of the following ways: * Send mail to mail-server@rtfm.mit.edu with the body containing "send usenet/news.answers/internet-services/access-via-email". * Send mail to mailbase@mailbase.ac.uk with the body containing "send lis-iis e-access-inet.txt". [ToC] ------------------------------------------------------------------------ 12. I do not have access to Usenet. How do I post and receive news? To receive rec.games.corewar articles by email, join the COREWAR-L list run on the Koth.Org list processor. To join, send the message SUB COREWAR-L FirstName LastName to listproc@koth.org. You can send mail to corewar-l@koth.org to post even if you are not a member of the list. Responsible for the listserver is Scott J. Ellentuch (ttsg@ttsg.com). Servers that allow you to post (but not receive) articles are available. Refer to the Accessing the Internet by E-Mail FAQ for more information. [ToC] ------------------------------------------------------------------------ 13. Are there any Core War related WWW sites? You bet. Each of the two KotH sites sport a world-wide web server. Stormking's Core War page is http://www.koth.org; pizza's is http://www.ecst.csuchico.edu/~pizza/koth . Damien Doligez (a.k.a. Planar) has a web page that features convenient access to regular newsletters (Push Off, The '94 Warrior, Core Warrior) and a well organized library of warriors: http://para.inria.fr/~doligez/corewar/. Convenient for U.S. users, this site is also mirrored at koth.org. [ToC] ------------------------------------------------------------------------ 14. What is KotH? How do I enter? King Of The Hill (KotH) is an ongoing Core War tournament available to anyone with email. You enter by submitting via email a Redcode program (warrior) with special comment lines. You will receive a reply indicating how well your program did against the current top programs "on the hill". There are two styles of KotH tournaments, "classical" and "multi-warrior". The "classical" KotH is a one-on-one tournament, that is your warrior will play 100 battles against each of the 20 other programs currently on the Hill. You receive 3 points for each win and 1 point for each tie. (The existing programs do not replay each other, but their previous battles are recalled.) All scores are updated to reflect your battles and all 21 programs are ranked from high to low. If you are number 21 you are pushed off the Hill, if you are higher than 21 someone else is pushed off. In "multi-warrior" KotH, all warriors on the hill fight each other at the same time. Score calculation is a bit more complex than for the one-on-one tournament. Briefly, points are awarded based on how many warriors survive until the end of a round. A warrior that survives by itself gets more points than a warrior that survives together with other warriors. Points are calculated from the formula (W*W-1)/S, where W is the total number of warriors and S the number of surviving warriors. The pMARS documentation has more information on multi-warrior scoring. The idea for an email-based Core War server came from David Lee. The original KotH was developed and run by William Shubert at Intel starting in 1991, and discontinued after almost three years of service. Currently, KotHs based on Bill's UNIX scripts but offering a wider variety of hills are are running at two sites: koth@koth.org is maintained by Scott J. Ellentuch (tuc@ttsg.com) and pizza@ecst.csuchico.edu by Thomas H. Davies (sd@ecst.csuchico.edu). Up until May '95, the two sites provided overlapping services, i.e. the some of the hill types were offered by both "pizza" and "stormking". To conserve resources, the different hill types are now divided up among the sites. The way you submit warriors to both KotHs is pretty much the same. Therefore, the entry rules described below apply to both "pizza" and "stormking" unless otherwise noted. Entry Rules for King of the Hill Corewar * Write a corewar program. KotH is fully ICWS '88 compatible, EXCEPT that a comma (",") is required between two arguments. * Put a line starting with ";redcode" (or ";redcode-94", etc., see below) at the top of your program. This MUST be the first line. Anything before it will be lost. If you wish to receive mail on every new entrant, use ";redcode verbose". Otherwise you will only receive mail if a challenger makes it onto the hill. Use ";redcode quiet" if you wish to receive mail only when you get shoved off the hill. Additionally, adding ";name " and ";author " will be helpful in the performance reports. Do NOT have a line beginning with ";address" in your code; this will confuse the mail daemon and you won't get mail back. Using ";name" is mandatory on the Pizza hills. In addition, it would be nice if you have lines beginning with ";strategy" that describe the algorithm you use. There are currently seven separate hills you can select by starting your program with ;redcode-94, ;redcode-b, ;redcode-lp, ;redcode-x, ;redcode, ;redcode-94x or ;redcode-94m. The former four run at "pizza", the latter three at "stormking". More information on these hills is listed below. * Mail this file to koth@koth.org or pizza@ecst.csuchico.edu. "Pizza" requires a subject of "koth" (use the -s flag on most mailers). * Within a few minutes you should get mail back telling you whether your program assembled correctly or not. If it did assemble correctly, sit back and wait; if not, make the change required and re-submit. * In an hour or so you should get more mail telling you how your program performed against the current top 20 (or 10) programs. If no news arrives during that time, don't worry; entries are put in a queue and run through the tournament one at a time. A backlog may develop. Be patient. If your program makes it onto the hill, you will get mail every time a new program makes it onto the hill. If this is too much mail, you can use ";redcode[-??] quiet" when you first mail in your program; then you will only get mail when you make it on the top 25 list or when you are knocked off. Using ";redcode[-??] verbose" will give you even more mail; here you get mail every time a new challenger arrives, even if they don't make it onto the top 25 list. Often programmers want to try out slight variations in their programs. If you already have a program named "foo V1.0" on the hill, adding the line ";kill foo" to a new program will automatically bump foo 1.0 off the hill. Just ";kill" will remove all of your programs when you submit the new one. The server kills programs by assigning an impossibly low score; it may therefore take another successful challenge before a killed program is actually removed from the hill.

If you just want to get a status report without actually challenging the hills, send email with ";status" as the message body (and don't forget "Subject: koth" for "pizza"). If you send mail to "pizza" with "Subject: koth help" you will receive instructions that may be more up to date than those contained in this document. At "stormking", a message body with ";help" will return brief instructions. If you submit code containing a ";test" line, your warrior will be assembled but not actually pitted against the warriors on the hill. At "pizza", you can use ";redcode[-??] test" to do a test challenge of the Hill without affecting the status of the Hill. These challenges can be used to see how well your warrior does against the current Hill warriors. All hills run portable MARS (pMARS) version 0.8, a platform-independent Core War system available at www.koth.org. The '94 and '94x hills allow five experimental opcodes and three experimental addressing modes currently not covered in the ICWS'94 draft document: * LDP - Load P-Space * STP - Store P-Space * SEQ - Skip if EQual (synonym for CMP) * SNE - Skip if Not Equal * NOP - (No OPeration) * * - indirect using A-field as pointer * { - predecrement indirect using A-field * } - postincrement indirect using A-field [ToC] ------------------------------------------------------------------------ 15. Is it DAT 0, 0 or DAT #0, #0? How do I compare to core? Core is initialized to DAT 0, 0. This is an illegal instruction (in source code) under ICWS'88 rules and strictly compliant assemblers (such as KotH or pmars -8) will not let you have a DAT 0, 0 instruction in your source code - only DAT #0, #0. So this begs the question, how to compare something to see if it is empty core. The answer is, most likely the instruction before your first instruction and the instruction after your last instruction are both DAT 0, 0. You can use them, or any other likely unmodified instructions, for comparison. Note that under ICWS'94, DAT 0, 0 is a legal instruction. [ToC] ------------------------------------------------------------------------ 16. How does SLT (Skip if Less Than) work? SLT gives some people trouble because of the way modular arithmetic works. It is important to note that all negative numbers are converted to positive numbers before a battles begins. Example: -1 becomes M-1 where M is the memory size (core size). Once you realize that all numbers are treated as positive, it is clear what is meant by "less than". It should also be clear that no number is less than zero. [ToC] ------------------------------------------------------------------------ 17. What is the difference between in-register and in-memory evaluation? These terms refer to the way instruction operands are evaluated. The '88 Redcode standard ICWS'88 is unclear about whether a simulator should "buffer" the result of A-operand evaluation before the B-operand is evaluated. Simulators that do buffer are said to use in-register evaluation, those that don't, in-memory evaluation. ICWS'94 clears this confusion by mandating in-register evaluation. Instructions that execute differently under these two forms of evaluation are MOV, ADD, SUB, MUL, DIV and MOD where the effective address of the A-operand is modified by evaluation of the B-operand. This is best illustrated by an example: L1 mov L2, mov.i #0, impsize Bootstrapping Strategy of copying the active portion of the program away from the initial location, leaving a decoy behind and making the relocated program as small as possible. B-Scanners Scanners which only recognize non-zero B-fields. example add #10, scan scan jmz example, 10 c Measure of speed, equal to one location per cycle. Speed of light. CMP-Scanner A Scanner which uses a CMP instruction to look for opponents. example add step, scan scan cmp 10, 30 jmp attack jmp example step dat #20, #20 Colour Property of bombs making them visible to scanners, causing them to attack useless locations, thus slowing them down. example dat #100 Core-Clear Code that sequentially overwrites core with DAT instructions; usually the last part of a program. Decoys Bogus or unused instructions meant to slow down scanners. Typically, DATs with non-zero B-fields. Decrement Resistant Property of warriors making them functional (or at least partially functional) when overrun by a DJN-stream. DJN-Stream (also DJN-Train) Using a DJN command to rapidly decrement core locations. example ... ... djn example, <4000 Dwarf The prototypical small bomber. Gate-busting (also gate-crashing) technique to "interweave" a decrement-resistant imp-spiral (e.g. MOV 0, 2668) with a standard one to overrun imp-gates. Hybrids warriors that combine two or more of the basic strategies, either in sequence (e.g. stone->paper) or in parallel (e.g. imp/stone). Imp Program which only uses the MOV instruction. example mov 0, 1 or example mov 0, 2 mov 0, 2 Imp-Gate A location in core which is bombed or decremented continuously so that an Imp can not pass. Also used to describe the program-code which maintains the gate. example ... ... spl 0, mov.i #0,IMPSIZE Mirror see reflection. On-axis/off-axis On-axis scanners compare two locations M/2 apart, where M is the memory size. Off-axis scanners use some other separation. Optimal Constants (also optima-type constants) Bomb or scan increments chosen to cover core most effectively, i.e. leaving gaps of uniform size. Programs to calculate optimal constants and lists of optimal numbers are available at www.koth.org. Paper A Paper-like program is one which replicates itself many times. Part of the Scissors (beats) Paper (beats) Stone (beats Scissors) analogy. P-Warrior A warrior which uses the results of previous round(s) in order to determine which strategy it will use. Pit-Trapper (also Slaver, Vampire). A program which enslaves another. Usually accomplished by bombing with JMPs to a SPL 0 pit with an optional core-clear routine. Q^2 Scan A modern version of the Quick Scan where anything found is attacked almost immediately. Quick Scan 2c scan of a set group of core locations with bombing if anything is found. Both of the following codes snips scan 16 locations and check for a find. If anything is found, it is attacked, otherwise 16 more locations are scanned. Example: start s1 for 8 ;'88 scan cmp start+100*s1, start+100*s1+4000 ;check two locations mov #start+100*s1-found, found ;they differ so set pointer rof jmn attack, found ;if we have something, get it s2 for 8 cmp start+100*(s2+6), start+100*(s2+6)+4000 mov #start+100*(s2+6)-found, found rof found jmz moveme, #0 ;skip attack if qscan found nothing attack cmp @found, start-1 ;does found points to empty space? add #4000, found ;no, so point to correct location mov start-1, @found ;move a bomb moveme jmp 0, 0 In ICWS'94, the quick scan code is more compact because of the SNE opcode: start ;'94 scan s1 for 4 sne start+400*s1, start+400*s1+100 ;check two locations seq start+400*s1+200, start+400*s1+300 ;check two locations mov #start+400*s1-found, found ;they differ so set pointer rof jmn which, found ;if we have something, get it s2 for 4 sne start+400*(s2+4), start+400*(s2+4)+100 seq start+400*(s2+4)+200, start+400*(s2+4)+300 mov #start+400*(s2+4)-found-100, found rof found jmz moveme, #0 ;skip attack if qscan found nothing add #100, -1 ;increment pointer till we get the which jmn -1, @found ;right place mov start-1, @found ;move a bomb moveme jmp 0, 0 Reflection Copy of a program or program part, positioned to make the active program invisible to a CMP-scanner. Replicator Generic for Paper. A program which makes many copies of itself, each copy also making copies. Self-Splitting Strategy of amplifying the number of processes executing a piece of code. example spl 0 loop add #10, example mov example, @example jmp loop Scanner A program which searches through core for an opponent rather than bombing blindly. Scissors A program designed to beat replicators, usually a (B-field scanning) vampire. Part of the Paper-Scissors-Stone analogy. Self-Repair Ability of a program to fix it's own code after attack. Silk A replicator which splits off a process to each new copy before actually copying the code. This allows it to replicate extremely quickly. This technique is only possible under the '94 draft, because it requires post-increment indirect addressing. Example: spl 1 mov -1, 0 spl 1 ;generate 6 consecutive processes silk spl 3620, #0 ;split to new copy mov >-1, }-1 ;copy self to new location mov bomb, >2000 ;linear bombing mov bomb, }2042 ;A-indirect bombing for anti-vamp jmp silk, {silk ;reset source pointer, make new copy bomb dat >2667, >5334 ;anti-imp bomb Slaver see Pit-Trapper. Stealth Property of programs, or program parts, which are invisible to scanners, accomplished by using zero B-fields and reflections. Stone A Stone-like program designed to be a small bomber. Part of the Paper-Scissors-Stone analogy. Stun A type of bomb which makes the opponent multiply useless processes, thus slowing it down. Example is referred to as a SPL-JMP bomb. example spl 0 jmp -1 Two-Pass Core-Clear (also SPL/DAT Core-Clear) core clear that fills core first with SPL instructions, then with DATs. This is very effective in killing paper and certain imp-spiral variations. Vampire see Pit-Trapper. Vector Launch one of several means to start an imp-spiral running. As fast as Binary Launch, but requiring much less code. See also JMP/ADD Launch and Binary Launch. This example is one form of a Vector Launch: sz EQU 2667 spl 1 spl 1 jmp @vt, }0 vt dat #0, imp+0*sz ; start of vector table dat #0, imp+1*sz dat #0, imp+2*sz dat #0, imp+3*sz ; end of vector table imp mov.i #0, sz [ToC] ------------------------------------------------------------------------ 23.

Anyone to enlighten me > what is going on? This goes in cycles. The hill is currently dominated by high-tie programs, silks and stone-imps. It is ripe to be picked by scanners which are high win/loss programs. When that happens the scores will spread out again.

As a small additional incentive, the winner of this round will receive the code for '88 test IV currently scoring quite well on the hill. Regards, John
