[computer-go] Bursaries for Computer Go

2009-12-09 Thread Steve Kroon
I have some bursary funding available for a computer Go project at Stellenbosch University in South Africa, at both masters and doctoral level. Although they would be useful, knowledge of machine learning/artificial intelligence techniques and skill in the game of Go are not necessary. However,

[computer-go] Fuego parameter question
