Re: Bruteforce_binbook
updated : bruteforce_binbook.exe (added : detection of consecutive out-of-books)
Since the tool was finding way too many unprotected lines and some were not often chosen, I realized that it was coming from a kind of "false" out-of-books, for example :
So now the tool will wait for 2 consecutive out-of-books before retaining the lines.

Re: Bruteforce_binbook
About the last uploded result :
(white_Olisfish 040623.bin played as white, Olisfish 040623.bin played as black, eman 8.40 played all out-of-book positions.)
337-4, atomized !
Ok now, how to get this kind of result ?
First, here are my settings :
my_computer.ini
In the positions for white to play, Eman analyzed each legal moves at D26.
In the positions for black to play, asmFish played all book's moves with a minimum weight of 10%.
Bruteforce_binbook only kept lines with a minimum evaluation of 50 cp.
Eman 8.40 64-bit BMI2.txt
Eman loaded/saved all its D26 scores into the work.exp file.
Then, i ran bruteforce_binbook.exe olisfish_040623.bin and i got these lines :
white_Olisfish 040623.lst
Then, i added 2 configurations in the engines.json file :
"white_Olisfish 040623 (Eman 8.40)" configuration
"Olisfish 040623 (Eman 8.40)" configuration
Then, i ran a little test with cutechess-cli :
3 x concurrency 12 => 36 threads on 40
3 x 400 games => 1200 games
run1.bat
run2.bat
run3.bat
(white_Olisfish 040623.bin played as white, Olisfish 040623.bin played as black, eman 8.40 played all out-of-book positions.)
