| welcome Angels 77 has sent us this
VadimVolkov Today 9:29 am Angels_77 - for this mod in sourece code I set TITANIC_MODE to always on. In TURBO is #define to 4 CPUS_SIZE, in TUNABLE can change as usual, but still always active titanic. Maybe some windows compile change these settings
Change in speed in my testing for TURBO+MINIMAL is 2-3% average only. Mostly in TURBO mode is removal of options to make code have less test-and-branch. This is only small fraction of work of program does, I am not expecting elo++ from this change. When run benchmark, I see normal speed 520k-530k NPS, with turbo speed 530k-540k. | |

| Angels77 [img] [You must be registered and logged in to see this link.][/img] sends angels_77 - the TUNABLE compile offers options for the change of Ivanhoe evaluation function. Easy option to explain is MaterialScale and PositionalValueScale multiplier. Understand for choose move, chess engine give a score for each position from many factor. These multiplier change what is important for decide the good move. MaterialScale increase cause Ivanhoe to multiply weight of eval of material, PositionalValueScale do same for eval of position factors. If set Positional high, Ivanhoe stop caring about losing pieces. If set MaterialScale high, Ivanhoe stop caring about good arrangement, only want to win the pieces. Piece alt values are only used if UseAltVals set, but then can change importance given different pieces. Make Ivanhoe love Pawns more than Queens! If UseAltVals and also MaterialOnlyEval is set, then Ivanhoe throw out all eval except material. Very very fast NPS, but also very stupid! Option AvoidDrawsIfLosing should change how Ivanhoe arranges pawns. Usual, if Ivanhoe has negative evaluation, it prefer pawn position for draw game and opposite when positive evalution. This parameter set make Ivanhoe not like drawish pawn position even if it behind. Other options for eval are very experiment. They are for turn on/off parts of eval function I only part understand. Make these options for study. These tests all come after main value is set and modify for special conditions, like EndGameEval test for material that == draw and set value 0. PawnWeightEval decide if care about drawish pawn structure (same as above) at all. Probable result for change these options is lower elo! For experiment and study they enjoy. VadimVolkov | |
