Next Core War Competition: none planned

This page holds some information for Core War events hosted by LUG@UCLA.

Reading Material

Preparation reading material to get new competitors up to speed:

  • Wikipedia article — some interesting background info, just skim the introduction.
  • FAQ — more relevant information, just read the first answer.
  • beginner's guide to Redcode — just read the section labelled "Starting with Redcode".
  • rock, paper, scissors, etc. — now that you have an idea how to write Redcode, here are some high level warrior techniques that may help you get started with designing your own warrior.

Competitor info

Your warrior source code will need some metadata in the header, like this:

;redcode-94
;name My Warrior
;author John Doe

MOV 0, 1

Replace "My Warrior" with the name you want to give your warrior, and "John Doe" with your name. We will be using the Redcode-94 standard as outlined in the beginner's guide linked above. Name the file mywarrior.red or similar.

Competition instructions

Once everybody has written their warrior code, the competition may begin.

The competition machine needs to have pMARS installed (the most official Core War simulator). Download it here, and install:

$ tar xf pmars-0.9.2.tar.gz
$ cd pmars-0.9.2/src
$ make

Now upload all the warriors to the battle machine and make them fight to the death:

$ ./pmars -b path/to/all/warriors/*

Or specify only two warriors for a 1v1 battle:

$ ./pmars -b path/to/warrior0 path/to/warrior1

Have a lot of fun!
