Crystallite 1.1a

[dorsz]

Crystallite is a simple modification of an old Crystal 3.1 by Joseph Ellis. Crystallite is made especially for fortress positions. It recognizes them better than Crystal 3.1, Crystal 3.2 and Crystal 4.0.

Crystallite 1.1a is the same engine as Crystallite 1.1 but it is faster: AVX2 (+4.3%), BMI2 (+5.8%), modern (+1.6%). The exception is base engine, where old 1.1 turned out to be faster than 1.1a by 7.5%, so this version remains unchanged.

Thanks for this, dorsz. I look forward to examining your fortress detection modifications.

With respect from Canada,

Whenever you want, you can contact me privately on engine-chess.

I will do that once I return home from a job related assignment.

I will need to register there first as I am not yet a member of Vernon's forum.

Thanks for Contempt 1000, gives fine mate search with NNUE- usage switched off

Pity 1.1a doesn't work with latest green NNUE of SF dev so far

It's not a pity. This net is intentional.
