But please note that using Pachi in this mode is not tested extensively, so check its performance in whatever version you test before you use it as a reference. +Note that even in this "basic UCT" mode, Pachi optimizes tree search +by considering board symmetries at the beginning. Currently, there's no +easy option to turn that off. The easiest way is to tweak board.c so +that board_symmetry_update() has goto break_symmetry at the beginning +and board_clear has board->symmetry.type = SYM_NONE. + Except UCT, Pachi supports a simple idiotbot-like engine and an example treeless MonteCarlo-player.
