SmarThink v1.97 is available

Post by Sergei S. Markoff » Thu Dec 22, 2016 12:00 am

SmarThink v1.97 — December 2016 release of the engine. Major changes:

— more agressive use of SEE for move ordering (even for non-captures);
— move generator changed to use magic bitboards;
— several search reduction improvements;
— adaptive aspiration window (based on depth and score);
— new TT entry priority scheme based on best move index;
— several optimizations;
— further eval tuning.

Estimated ELO gain: +30-50

Those long arms strike fear in my heart. But the game becons. Can I refuse such a lady, even in the shadows of clear and present danger?

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

There are 5 versions in the ZIP file. The x32/x64 bit is obvious but what is the difference between the SmarThink_v197_x64.exe & SmarThink_v197_x64_standalone.exe?

_standalone means no /Qparallel option, so it's 3% slower but don't need Intel redistributable DLL's package installed.
