Whats Shash MCTS ?
Parent - By user923005 (****) Date 2019-02-21 19:15
MCTS stands for Monte Carlo Tree Search.
It is the search method pioneered by Go programs.
It is very popular with the GPU versions of chess programs.
I do not know if the SHASH program uses the GPU.

1) "Whats Shash MCTS ?"

2) "I do not know if the SHASH program uses the GPU."


1) It is ShashChess with the MCTS option checked. Sorry, I should not use my own abbreviations.

2) I do not know either, I do not have any GPU at all (just the obsolete ATI Radeon 4250 chip physically in my motherboard for its basic DX9 display).
