Here's a 3D MDS map of the top 100 warriors from the 88 Koenigstuhl. Each point represents a warrior. The closer a point is to another point, the closer the warriors' scores are. #corewar

Has anyone got access to the issues of Tudomány (the Hungarian edition of Scientific American) with A K Dewdney's Számítógépes Észjáték columns about Memóriaháború (Core War)? Thanks #corewar

"Windows Hothouse, Creating Artificial Life with Visual C++" by Mark Clarkson (1994) has a chapter on Core War.

Inversed has computed the Nash equilibrium for the tiny hill. Ranking is by probability with all warriors scoring the same. For more details, see "Nash equilibrium: Tiny 2022.03.23

Are there any warriors similar to Gamma Paper 3.0 which bomb with a small stone then switch to paper? Apart from Gamma Paper I've seen Smooth Noodle Map, Killer Instinct and Leapfrog. #corewar

Are there any warriors similar to Hydra and the Living Dead series which launch multiple copies of very similar tiny bombers / clears? #corewar
