When I modified the corewars evolver program, RedRace, to work in a warming simulation I was surprised at how odd bugs and flaws in the simulation program seemed to jump out at me. My favorite was when the weak defending forces evolved to exploit a quirk in the rules that let them win, if they all died very quickly. The Easter Egg Hypothesis: complex software system are likely to contain flaws or vulnerabilities which are hidden from plain sight. They can avoid detection for a long time because they fall within psychological blind spots. They only seem obvious in hindsight. Co-evolutionary simulation can help find these problems by leading one to focus on important aspects of the system that common sense says should be ignored. The gimmick behind the abusive warriors is the fact that the hills at KOTH and PIZZA use -F numbers and so the "random" warrior locations are easily predicted. Certain Abuse, below, was designed to be strong as a challenger but helpless as a defender: the "expiration date" effect. Later warriors in the series were equally strong challenging or defending, but didn't last much longer because they only worked well against certain kinds of warriors. Pizza's -F number was calculated by sending a number of probe warriors to the hill. An exhaustive search was then used to find an -F number whose results against published warriors were identical to those returned by Pizza. Later, I discovered Nathan Green describes a hand-shaking method for calculating the -F number in Core Warrior #30. After Certain Abuse's outing on the hills, a patch was created for pMars to prevent future exploitation of -F numbers. Here's the code you've been waiting for: ;redcode-94 ;name Certain Abuse ;author Dave Hillis ;strategy - Takes advantage of the fact that the 94 hill and the ;strategy - Beginners hill both used -F 4000. It uses a P-space ;strategy - round counter and a look-up table to tell where the ;strategy - second warrior will be loaded into core. This version ;strategy - is only effective when challenging the hill. To fight ;strategy - as a defender, you have to use the negatives of the ;strategy - table values. The program is optimized to kill the ;strategy - published warriors that were on the 94 hill. ;assert CORESIZE==8000 org START counter equ #-109 off equ 100 wrap equ 87 target1 equ target2-1 target2 equ thecnt START thecnt ldp counter, #0 ; increment a round counter add #1, thecnt stp.b thecnt, counter add.ba thecnt, bomber slt.ab #wrap, thecnt jmp bomber add.a #-wrap, bomber mov.x *bomber, *bomber bomber mov.i b-1, target1 add.f target1, target2 ; target2 and target1 hold the start and end points of the other warrior. ; Attack it by shuffling lines from both ends working towards the middle attack mov.i }target2, {target1 mov.i {target1, }target2 djn.b attack, #121 b spl.i #4000+off,<4994+off ; The abuse table.

Enough is Enough is a p-spacer, which hopes to score well against either a defensive or agressive hill. A tried and tested, age old formula is uses by EiE: switch between a paper and scanner. Other successful warriors using this technique include Fire and Ice, and Origami Harquebus. The paper uses a similar principle to nPaper, but is aimed against stone/imps with b-driven imps such as Quicksilver, Uninvited etc. This is not a general purpose paper, and was never designed to perform well against scanners. The scanner combines Zooom's speed up trick with a scanner somewhat alike to the one found in Recycled Bits. A step of 903 is chosen to hopefully perform well against either 3 or 7 point imps in silk/imps. The switcher is a P^3 multi-boot. The stp instruction is left as late as possible so the warrior is less prone to accidental brainwashing, by a q-scanner for example. The scanner is played if the paper loses often. If the paper ties regularly, the scanner is given a 1 round trial to decide whether it should be played or not. The paper component scores 35% wins, 60% ties against Quicksilver. The scanner scores 21% wins and 8% ties. Enough is Enough scores 34% wins and 49% ties. In this case, the switcher is effective 9 times out of 10. The paper component scores 2% wins and 94% ties against Safety in Numbers. The scanner scores 41% wins and 31% ties. Enough is enough scores 31% wins and 48% ties. The switcher is effective 8 times out of 10. So here it is: ;redcode-94 ;name Enough is enough! ;author John Metcalf ;strategy had enough of tweaking the scanner and switcher :-( ;strategy p-switcher, switch between scan and paper ;assert (CORESIZE==8000) org pThink ; -=> Switcher <=- paper equ (silk-silk) scan equ (silk-sAtk) wSize equ 9 pThink: ldp.a {pBoot-323, #1 ldp.a Scanner <=- sStp equ 903 sAtk: mul.x {sJmp-1, }sAlt sPtr: slt.ba #9, #0 mov.b @3, sAtk sAdj: mov sSpl, >sAtk sAdd: add #sStp, sPtr sJmp: jmz.f sAdd, @sPtr sAlt: jmn sAtk, sPtr jmp sAdj, }sAdj sSpl: spl #0, {0 ; -=> Paper <=- pStep1 equ 2852 pStep2 equ 5213 x equ 6580 y equ 2951 silk: spl *0, >1803 spl 1, >3109 spl 1, {2506 pap1: spl @0, >pStep1 mov.i }pap1, >pap1 mov.i #y, <1 mov -1, {x mov.i {pap1, pStep2 end _______________________________________________________________________________ Questions?
