Re: New engine: a0lite

FWIW, I ran a couple of my crazy tests.... and the results showed my assumption to be more or less exactly wrong. Only incrementing visit count for own moves turned out much worse, while only doing it for opponent moves turned out about equal (in my very limited sample size). My guess is that when t...

Re: Crystal Update

I have added one more very minor update, which includes the following: 1) Correct scoring support for 7 piece TBs 2) Put a few example positions in the readme for the inevitable question: why Crystal? 3) Retired razoring.... it was barely worth any Elo, (even tested better without it at LTC for me),...

Re: Crystal Update

I created a release with a couple of compiles IpMan has done. https://github.com/jhellis3/Stockfish/releases/tag/v2.0 One of my favorite things about it is this position: 8/1p1pNpbk/1q1P4/pP2p2K/P3N3/4P1P1/3P4/8 w - - I actually did not realize it finds it (less than 180s single thread) when I made ...

Crystal Update

For those who may find such things useful: The changes since last release are pretty minor but not insignificant. 1) Small tweak to the "fortress detection" code 2) Better effort to output a sensible PV for only moves 3) More robust king danger detection in search 4) Latest upstream Stockfish merged...

Re: Mate solving comparison (10 - 19 moves)

Hey Mike, do you happen to have a branch up with this new multi-pv code? I would like to study it a little :).

Re: New engine: a0lite

Ok, I've forked it, done some tinkering, and I *think* I have badgyal installed and working properly. Played a few games against Crystal and it seems to make mostly reasonable moves before getting destroyed. I am not very familiar with python though.... been at least 20 years... Question: Once I mak...
