Tournament of the surviving 1993 CoreWar programs

A reproduction, not the original competition results

Generated on 2026-09-27 by report.py from runs.csv.

These are not the results of the First Hungarian Memory War (CoreWar) Championship of 1993. Some programs here were never entries (by their own comments MICE and CHANG are the winner and runner-up of the 1985 championship). This is a new tournament played in 2026 between the programs found in the Historical folder, so the ranking says nothing about how the original competition ended.

Setup

Engine: Viktor’s MARS.COM (CoreWar MARS V1.0 by GM, 1993) running in DOSBox in statistics mode (/P, /V). This is not COREWAR.EXE, the reference implementation by Kovács Tamás, one of the organizers.
The rules follow the 1993 championship rules in SZABALY.TXT: 8000 cell arena, at most 64 processes per program, programs may execute each other’s code, and a war is a draw after 600000 steps.
36 programs, 630 pairs, 1000 games per pair (half of them with each program starting first), 630000 games in total.
Start order: over all games the program starting first won 157527, the second one won 158283, and 314190 games were draws.

Scoring

Elo is a maximum likelihood Bradley-Terry rating on the Elo scale (400 points means 10:1 odds), where a draw counts as half a win. It is fitted to all games at once, so unlike a running Elo it does not depend on the order of the games. The average rating is 1500. Each pair gets one extra virtual draw, which keeps the rating of a program that never scores finite.

Points use the usual CoreWar tournament scoring: 3 for a win and 1 for a draw, averaged per 100 games (at most 300). Score % is wins plus half the draws as a percentage of the games played.

Example battle

MICE (cyan) against KILLER (magenta), 14000 steps in. The bars at the bottom left show the number of processes of each program, the counter on the right shows the game number and the steps in thousands. Videos: opening, slowed down and full game at 286 speed.

Ranking

The ranking is by Elo.
