asmfish was updated to this commit in the last 3 weeks:

https://github.com/official-stockfish/S ... /pull/1798 ( date 11/4/2018)
I run my own build file, that builds the standard, matefinder and variety play versions for all operating systems and supported CPU types in 66 seconds, zips them up and places the zip file by operating system into the appropriate folder ( the build script is also on my fork GitHub if you are interested in the macOS_build tree)

Code: Select all

How do the variety binaries differ from the regular binaries?

The engine will not always play the best move, but will vary its move. As one might expect, the engine will also play weaker,

The asmfish team incorporated a variety function in their code that can only be enabled during the build process,. i.e., even with single thread, it will not play the same moves over and over again. How much variety and what it will play depend on the position of course and how much time you give it. By definition, variety play will play weaker as it does not always play what it thinks is the best move , it is designed for human play against the engine to have games that do not repeat regardless of the opening you are playing.

From the asmfish GitHub page:

"Variety: In QSearch, if the score is in the range [-4v, 1000+4v), add a pseudorandom integer from (-4v, 4v) to the score."
