Perft for Checkers for Depth 27
With the new improvements in place, it would almost be a waste not to go deeper with my perft for checkers computation . Therefore, I computed perft(27) from the initial position of 8x8 checkers. Below you see the perft breakdown per move, called "divide". As stated before, these numbers were computed on a cluster of machines, further optimized with a "hard collision"-free transposition table as well as bulk counting. The move generator does not eliminate duplicate captures. move divide(27) ------------------------------ - 12-16 = 516399283859880203 11-16 = 519502096014967805 11-15 = 476666239516455180 10-15 = 468705060101275533 10-14 = 400425747281243848 9-14 = 486493422418651579 9-13 = 631652334435528457 ------------------------------- perft(27) = 3499844183628002605 The implementation is "fault tolerant" against machine failures. Nevertheless, since I saw a few of these recove
