Re: [Computer-go] Strong engine that maximizes score

Thanks for your answer. Unfortunately Pachi doesn't seem to really try to maximize score, even with these settings: Once one side has won by a large enough margin, it will stop trying to kill small groups and I am precisely trying to generate a database to learn about life and death. Perhaps I

After reading the relevant code, I realized that val_scale=1.0 should do precisely what I wanted. I have tested it a bit, and so far so good. Thanks! Álvaro. On Tue, Nov 17, 2015 at 7:12 AM, Petr Baudis wrote: > Hi! > > On Tue, Nov 17, 2015 at 07:05:34AM -0500, Álvaro Begué
