Huh, why not use Pascal? It has speed of C and simplicity of Java :) heck, you could use perl. plenty of packages available (it can even be made multithreaded!), shared memory packages, etc. i mean, if speed isn't your top concern... i think speed is one of most important things beacuse

Orego version 3.03, described in the paper and available at the Orego web site, is in C++. However, we are finding C++ an exceedingly frustrating language to work in. I won't go into the details here -- we don't need another language war -- but suffice it to say that it seems like we're

Greetings, I would like to thank You for all your sugestions. Some of them still awaiting implementation ;-) I've started from implementing Alpha-Beta pruning but I would like to ask You how to chose moves which should be evaluated first? My simple idea is to analyze first moves near the last mo

Greetings guys. Ive implemented standard minimax algorithm but is so enormous slow even on 9x9 board. For example when depth = 3 (player1 move, player2 move, player1 move) computing time at the begining is like 1 minute. I know that I should implement alpha-beta pruning variation to speed up it b

Hello guys, I am trying to write my first GO program and I have few difficulites. Could someone give me any examples / hints about the evaluation function? How to evaluate curret state of the game? I am writing my engine based on article in: http://en.wikibooks.org/wiki/Computer_Go/Represent
