This article is about a software re-creation of the Go board game. For the Google-sponsored programming language also known as golang, see Go (programming language). For the different, older programming language by Francis McCabe, see Go! (programming language).
At this level of performance, GnuGo was between six and seven stones weaker than the top commercial programs on good hardware as of early 2009, but comparable in strength to the strongest programs not using Monte Carlo methods. It did well at many computer Go tournaments. For instance, it took the gold medal at the 2003 and 2006 Computer Olympiad and second place at the 2006 Gifu Challenge.
