SmarThink v1.90 is available

Post by Sergei S. Markoff »

SmarThink v1.90 — March 2016 release of the engine. Major changes:

— additional endgame patterns recognition;
— improved beta pruning for depth = 1 nodes;
— fixed bug in "semi-interior node" recognition;
— better check evasions ordering;
— several optimizations including combined middlegame/endgame int eval vector;
— further eval tuning;
— development patterns handling.

Estimated ELO gain: +30-40.

It is the common and forever question)
At practice, current SmarThink data structures are ready for SMP, moreover in eval tuning mode it is SMP. But the final step — to implement something like YBW or Jamboree is still too stressing for me. I hope I will have enought courage to make it in 2.00 :)

Just try lazy SMP, it works well (contrary to what people say), even SF people switched from YBW to lazy some time ago :)

Are you ok with previous version?..
I have Fritz14 GUI and it works well with ST. Have you tried to simply run engine executable?

libiomp5md.dll is needed.

PS: With the installed DLL-File I now can load the engine, but it doesn't run (also Fritz GUI).

I always get this problem with SmarThink - it never runs in Fritz.

Strangely with Fritz-8-GUI, everything is fine for me. With Fritz-7-GUI not.
