//! Outer-Open Gomoku is a board game which is a enhanced version of connect5 (Gomoku).\ //! The game is a two-player game which played on a 15x15 Go board.\ //! Two players take turns placing a move on an empty intersection in this board.\ //! The winner is the first player to form an unbroken chain of five moves horizontally, vertically, or diagonally.\ //! Unlike Gomoku, the first move is required to be placed at the two outer rows or columns of this board.\ //! This program provides an AI playing with Minimax search with alpha-beta pruning which uses //! patterns on evaluation.\ //! The avx512 intrinsic can do 32 pattern matching at one time.\ //! This avx512 is tested with non-avx512 code to verify its correctness.\ //! //! On Intel i7-7800x using single thread with fixed AVX-512 clock at 4.0GHz, the avx512 is speed up about 9x.\ //! The average time for each move in the avx512 is around 14.00s ± 1.31s and in the non-avx512 //! is 129.02s ± 4.96s.\ //! On Intel Tiger Lake i7-1165G7, the avx512 is around 11.11s ± 1.31s. //! //! Pattern Matching\ //! Use 512-bit to present the board state. The location 0 is top left.\ //! 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15\ //! 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31\ //! ...\ //! Pattern "OOOOO" is matching through "0 1 2 3 4", "1 2 3 4 5", ...\ //! Using avx512, "0 1 2 3 4", "16 17 18 19 20", ... can be matched simultaneously.\ //! //! //! You can test out this program via: //! //! cargo +nightly run --release --bin connect5 //! //! You should see a game self-playing. In the end of the game, it shows the average time for //! each move. #![feature(stdsimd, avx512_target_feature)] #![feature(stmt_expr_attributes)] use rand::seq::SliceRandom; use rand::thread_rng; use
