posdraw detection
cirebonb opened this issue · comments
asmfish will going faster if posisdraw detection on searchmacro and qsearchmacro moved to move_do and move_do_null, no functional change, no differ in bench, but increase n% on speed. ex.
call move_do
test ecx, ecx ;pos is draw?
jz .undo_move
;pruning
;search nonpv with reduction depth
;search pv with red depth
,search pv with normal depth
.undo_move:
mov ecx,dword[.move]
call move_undo
nah?
I just allready did it, change in uci.asm especially posisdraw func, change in search macro especially in state.pv initialize, move_do_search, move_do_probcut,move_donull, move_do.asm adding posisdraw at end/right after setcheckinfo, move_do_null.asm at end before setcheckinfo, and thereis code on uciparsemove with mention setcheckinfo twice, I strip one code call setcheckinfo right after move_do_uciparsemove, and tested it on intel i7 2,2, its extremely fast..., reaching above 5million nps on drawish endgame,
my plan in near future with permission of God, I will add queen mate detection on evaluation, evaluation will provide VALUEMATE-ONEPLY, this issue should be consider as prority, because in some cases, asmfish need much time to find solution in test ex. wac.epd, but actually I didnt have much time to spend, this is my problem, not you guys.
"Its Not Fair",
That's very nice..can i test your asmFish version ;)
Allready tested.

dont worry, the picture is fake, ASMSF180313vk not ready in critical time bro... do it just for fun. thanks Ipmanchess, i still improve this source code just like imention above...
If it's fake?..why you put it here then on Github??
