Re: Tunguska 1.1 STS test results - improve eval

Yep, I'll try these things out. Actually, I have disabled many eval terms, either because they are not tuned or because they lose ELO. Mobility is a example that loses ELO. That is surprising as mobility typically adds a very significant amount of Elo to most alpha-beat chess programs. I wonder if ...

Re: Nice Mate in 4 that I missed at the finish line

Isn't it a slightly longer mate?

Re: NUCLEUS

I'm really glad this is getting more attention. There is much scope for research here, and different schemes could also be tried. One option which would be most useful IMHO would be to divide the resources by CPU, i.e. run the slaves concurrently on different CPUs. There is potentially more to gain ...
