Issue 44 September 23, 1996 ______________________________________________________________________________ Core Warrior is a weekly newsletter promoting the game of corewar. Emphasis is placed on the most active hills--currently the '94 draft hill and the beginner hill. Coverage will follow where ever the action is. If you have no clue what I'm talking about then check out these five-star internet locals for more information: FAQs are available by anonymous FTP from rtfm.mit.edu as pub/usenet/news.answers/games/corewar-faq.Z FTP site is: ftp.csua.berkeley.edu /pub/corewar Web pages are at: (Please note new Stormking's address) http://www.koth.org/ ;Stormking http://www.ecst.csuchico.edu/~pizza/koth ;Pizza http://pauillac.inria.fr/~doligez/corewar/ ;Planar Newbies should check the stormking page for the FAQ, language specification, guides, and tutorials.

After a forced break in late summer, due to Pizza maintenance, the 94 hill has gone back to his standard level of activity; don't be fouled by the small number of new warriors, more than 50 test that would have made the hill have been submitted. The test option proved in fat very popular even if there are a few drawbacks; one is that the aging of warriors cannot be ompared with that of past ones being now far more difficult. The second is that opponent don't have chanes to challenge a warrior under test, as Paul Kline pointed out, until it's released in offiial form. Last, as I experimented, a test warrior can score very different once it's released, this because test works on but 100 fights and the real fight on 200, and I'm not very lucky having lost more than 10 points :-( Steven Morrell volunteered to recalculate the hall of fame removing unnatural aging from the scores one we agree on a method to do it. The better one seems to disount aging if the pushed off warrior has an score under a treshold; I proposed 125 but Planar told me that some warriors, Impfinity to tell one, have been pushed off with lower scores. Having to set one, to allow Steven start his work, what about 120. Another hot topic in the newsgrou is if there is a need of a central organization, to take the place of the near dead ICWS, or if we can go on without it. The discussion is still hot. For those loving the old 88 redcode standard; it's worth noting that the 88 hill, available at koth@koth.org (Stormking), has a new leader with an incredible 17 pts lead. Congratulations to David Moore for his Racer X. --Beppe Bezzi ______________________________________________________________________________ Current Status of the Internet Pizza Server ICWS '94 Draft Hill: Hill Specs: coresize: 8000 max. processes: 8000 duration: after 80,000 cycles, a tie is declared. max. entry length: 100 minimum distance: 100 rounds fought: 200 instruction set: ICWS '94 Draft The current ICWS '94 Draft hill: # %W / %L / %T Name Author Score Age 1 40.3/ 19.0/ 40.7 Gigolo Core Warrior staff 161.6 1 2 38.8/ 20.2/ 41.0 unrequited love kafka 157.3 45 3 42.8/ 32.0/ 25.2 CC Paper Franz 153.5 4 4 42.1/ 32.0/ 25.9 Frogz Franz 152.2 5 5 31.5/ 14.8/ 53.7 Return Of The Jedimp John K W 148.2 113 6 44.1/ 40.6/ 15.3 Blur 2 Anton Marsden 147.6 124 7 42.8/ 40.2/ 17.0 Goldfinch P.Kline 145.3 66 8 42.4/ 39.4/ 18.2 Probe Anton Marsden 145.3 125 9 31.5/ 19.7/ 48.8 Rosebud Beppe 143.2 798 10 35.9/ 28.6/ 35.6 Simple v0.4b Ian Oversby 143.2 76 11 38.7/ 35.3/ 26.1 Flimsy v0.5c Ian Oversby 142.1 6 12 43.4/ 47.2/ 9.4 Q^2 Miro Anders Ivner 139.6 175 13 30.0/ 20.5/ 49.6 Impish v0.1 Ian Oversby 139.4 2 14 39.3/ 39.3/ 21.4 mrb-test m r bremer 139.4 31 15 39.1/ 40.2/ 20.7 Test Anton Marsden 138.1 35 16 25.1/ 12.6/ 62.3 ompega Steven Morrell 137.6 240 17 33.8/ 30.3/ 35.9 Jack in the box II Beppe Bezzi 137.2 482 18 33.8/ 30.7/ 35.5 Falcon v0.3 Ian Oversby 136.9 30 19 38.3/ 40.3/ 21.4 Instant Wolf 3.4 Edgar 136.4 8 20 37.8/ 39.8/ 22.4 Inferno 2.4 Philip Kendall 135.9 3 21 36.1/ 39.0/ 24.9 T.N.T. pro Maurizio Vittuari 133.2 843 22 39.6/ 46.2/ 14.2 Earthquake v0.2 Bjoern & Ian 132.9 82 23 38.3/ 45.3/ 16.3 myVamp5.5 Paulsson 131.3 15 24 35.7/ 40.7/ 23.6 Yogi Bear P.Kline 130.8 329 25 36.7/ 44.0/ 19.3 BackFromVacation Edgar 129.5 17 Weekly age: 15 ( 9 last issue, 9 the month before ) more than 50 test New warriors: 8 Turnover/age rate 53% Average age: 146 ( 174 last issue, 180 the week before ) Average score: 142 ( 136 last issue, 142 the week before ) The top 25 warriors are represented by several authors :-) Sorry, I don't have the patience to fill in the details this week. Lots of new warriors in the top position. Bezzi made many test during the week, some of which scored very high, to shodown with the new King, Gigolo, a cooperative warrior made with the others of Core Warrior staff. Don't ask him why after scoring 12 points over the second his warrior setted with but three unless you want to learn some new Italian words :-) Kafka's unrequited love loses top position after two weeks of domain, but remains near the top. Franz puts two warriors in top ranks, both using the qscan->silk combination; perhaps replicators are back vith vengeance. Q^2 scans are dominating the hill at expense of pspacers. ______________________________________________________________________________ 94 - What's New # %W / %L / %T Name Author Score Age 1 37.2/ 19.8/ 43.0 Gigolo Core Warrior staff 154.5 1 2 42.8/ 31.4/ 25.8 Frogz Franz 154.3 1 4 41.5/ 32.9/ 25.5 CC Paper Franz 150.1 1 5 39.3/ 35.2/ 25.5 Flimsy v0.5c Ian Oversby 143.3 1 8 38.9/ 39.3/ 21.8 Instant Wolf 3.4 Edgar 138.5 1 13 27.4/ 21.5/ 51.1 Impish v0.1 Ian Oversby 133.3 1 17 36.6/ 41.0/ 22.4 Inferno 2.4 Philip Kendall 132.1 1 17 37.9/ 45.4/ 16.7 myVamp5.5 Paulsson 130.5 1 Revolution in the first spots, we have a new 1st, 3rd and 4th. ______________________________________________________________________________ 94 - What's No More # %W / %L / %T Name Author Score Age 26 35.3/ 45.6/ 19.1 Twister Beppe Bezzi 125.0 575 26 23.6/ 21.1/ 55.3 Armory II John K W 126.0 257 26 1.5/ 1.7/ 0.8 myVamp5.4 Paulsson 5.4 159 26 0.2/ 1.0/ 2.8 September Beppe 3.4 21 26 36.1/ 46.9/ 17.0 Violent Micro v0.4d basehead 125.2 16 26 1.8/ 1.8/ 0.4 Instant Wolf 3.4 Edgar 5.9 15 26 1.6/ 2.1/ 0.3 Flimsy v0.5a Ian Oversby 5.2 14 26 4.0/ 2.5/ 1.5 Atom Smasher 2 Anton Marsden 13.5 3 Twister leaves us at the age of 575 and Armory at 257; all other are very young or killed by the author. ______________________________________________________________________________ 94 - What's Old # %W / %L / %T Name Author Score Age 21 36.1/ 39.0/ 24.9 T.N.T. pro Maurizio Vittuari 133.2 843 9 31.5/ 19.7/ 48.8 Rosebud Beppe 143.2 798 17 33.8/ 30.3/ 35.9 Jack in the box II Beppe Bezzi 137.2 482 24 35.7/ 40.7/ 23.6 Yogi Bear P.Kline 130.8 329 16 25.1/ 12.6/ 62.3 ompega Steven Morrell 137.6 240 Rosebud keeps his position while T.N.T. pro and Yogi lose some spots and Jack a few.

Against the qscan the only defence is booting away as fast as you can, little else to say. Against stones, apart being a replicator, one have to be resistant against decrements/increments and djn streams, I'll speak of that in future. Against imps the best defence is a good gate. 94 standard allows combining the gate with a forward running coreclear, but there are a few different ways to do that, what's the best ? I ran a few test pitting the more common gate clears against some different imp spirals; the spirals are all 3 points, 8 processes, binary launched and differ but in the imp instruction: Spiral #0,2667 mov.i #0, 2667 Spiral #1,2667 mov.i #1, 2667 Spiral #-1,2667 mov.i #-1, 2667 Spiral #2667,*0 mov.i #2667, *0 One can think that the first three will behave in the same way, but that's not true as we'll see. The last one is a different kind that's getting more and more popular; it's the a-driven imp, used by Die Hard and now by Rosebud. Now the clears. All those clears can easily be fitted inside your favourite bomber or scanner. ;name gate c-c1 gate1 equ (gate-5) org start for 10 dat 0,0 rof dat -5, 100 gate dat -5, jump-gate1+5 spl #-5, jump-gate1+5 for 10 dat 0,0 ;the warrior goes here rof start spl #-10,#10 mov @jump,>gate1 jump djn start+1,{gate+1 That's the clear used by Torch 18 and Thermite 2, just to say two successful warriors, it's a two pass spl/dat clear, switching to dat one its djn stream derements the b-field of 'jump' line.
