Perft for Checkers for Depth 25
Continuing my quest for deeper and deeper perft numbers for 8x8 checkers , I now computed depth 25 with the same distributed implementation I used earlier for depths up to 24. Below you see the perft breakdown per move (called "divide") from the initial position for depths 23, 24 and 25 (my depth 23 and 24 numbers were recently kindly confirmed by Murray Cash at the World Draughts Forum ). move divide(23) divide(24) divide(25) -------------------------------------------------------------- 12-16: 1123463594881857 5192042148594780 24019313789608561 11-16: 1131373985922218 5248615918291379 24153215782987793 11-15: 984253557821317 4602138522979438 21659601983574539 10-15: 1000606302770349 4643700995955222 21609957136212495 10-14: 856779998157523 3988937724259353 18496978526984076 9-14: 1003310451936358 4712325943133747 22101040287502927 9-13: 1337748969176591 6263620622082081 29027372375205409 --------------------------
