SlowRenju

I have been developing SlowRenju, a gomoku AI engine since Jan 2012, which is based on iteratively deepening alpha-beta pruning algorithm with a transposition table. SlowRenju has been participating in the Gomoku AI programming tournament Gomocup since 2013, which is one of the more famous computer gomoku tournament now.

Gomoku, also known as Five In a Row or 五子棋, is a game playing on a 15×15 (or maybe larger) board. Two persons put their own stones on the crossing of the board alternatively, and the game ends with a player winning by creating a line of five stones horizontally, vertically or diagonally, or with a draw by the board filled up with stones. There are also some variants of gomoku, among which the most famous one is renju, in which the black player (the player who moves first) loses by creating a double-three, a double-four or an over-line.

SlowRenju can support freestyle gomoku rule, standard gomoku rule and renju rule.

SlowRenju has been open-source on Github since May 2019. It is distributed under the GNU General Public License v3.0.
