Writing Software to Play the Ancient Game of Go

Wikipedia has related information at Computer Go

Go is a strategic, two-player game that originated in ancient China thousands of years ago. It is popular throughout East Asia, and is gaining popularity among computer programmers because of its extraordinary complexity. Whereas the top chess-playing computer programs are now better than the top human grand masters, the best Go-playing computer programs currently in existence can be defeated even by amateur Go players.

The rules of Go are simple, but the strategies complex; the sheer number of legal moves at any point in the game make programming an effective opponent a daunting task. This book endeavors to help the novice who is beginning to write software to play the ancient game of Go, as well as to provide a useful resource to those already skilled in the art.

The Go Community

It is becoming very common for Go players to use the Internet to meet, discuss games, and play one another. Many strong players now regularly play Go online. There is also a growing community of people who write Go software programs, with regular competitions and tournaments between the various Go-playing engines.
