Christian Schmidt recently announced the Second International Corewar Programming Contest with a concept similar to the new DynaHill.
The hill will be initialised with a pool of 3800 published warriors. Entries will compete against programs in their neighbourhood and move up or down depending on their score.
An interesting twist is the chance to enter warriors in 8 different categories including '94, '88, LP and nano. For full details of the rules see the official tournament page.
The deadline is 15th September. Good luck :-)
