MCTS implementation question

I'm working the code for an MCTS implementation. I'm coding Tic-Tac-Toe as an easy GAME to work out the bugs. I'm running into a situation where either: 1. The code is working fine and i'm just not sure what to do 2. I haven't implemented something correctly (usually this one! LOL) The question has ...

Re: Opening book read speed

I think you should consider converting your current format into something more efficient. See for example https://github.com/sshivaji/polyglot - supports reading/writing Polyglot book format (GPL). --Jon I agree. There are many FREE tools out there to create and maintain opening books in the polygl...

winboard.nl tournaments and Arena

"We" have one bishop, and the goal is to make it easier for it to move around, so we want more of our pawns on the opposite color. we can't control what the opponent does. 2. if we have zero or 2 pawns, then moving around pawns doesn't help our bishops, but, it can punish the opponent's single b...
