Re: tomitankChess 3.0

Really nice progress!! I'll include it in my next CCLS Season. One thing though, I think you're being a bit optimistic with ratings. CCRL has listed tomitankChess 2.0 64-bit at 2616 and in my own rating list (which is very similar to CCRL) it's at 2576. You might want to review your numbers :mrgree...

But you still prune bad SEE move in qsearch right ?
Yes, but only if i'm not in check! When i'm in check, then i call evasion moves and i don't pruning.

Earlier i used "See" for the evasion moves sorting, but it's was futile also.

Re: Playing transposition table moves in the Quiescence search

I came to the conclusion that only at the horizon is worth checking the transplant table. if (depth == 0)
Beyond that, it's very rare to help. It's just a waste of time..

The Mvv-Lva sorting is good enough in qsearch and hash move is futile (IMO)

Re: testing consistency

Recently I am getting inconsistent results from testing at various time controls/conditions. For example, one candidate change gave these results: SPRT against master (1 opponent), 60+0.6 time control: significant + (H1) after about 3800 games. Hyper-bullet, 40000 games against 5 opponents: -2 ELO ...

Re: Particle Swarm Optimization Code

For machine learning, the standard algorithm is Stochastic Gradient descent (SGD). I think the SGD is an wrong name. Just simply GD is the right name.
