faulty Hash option #3

Closed tissatussa closed 2 years ago

tissatussa commented 2 years ago

i just compiled the newest source code into a valid Linux binary and it works in CuteChess.

however, in the CuteChess settings i see that the Hash value can not be set, it can only be reset to its default value (512 Mb). it seems you did not properly define the Hash option :

UciOptionMap({'Hash': Option(name='Hash', type='spin', default=512, min=None, max=None, var=[])})

'min' and 'max' are None, which gives this error : the up / down counter form element does not work .. please correct this.

sure.

today i'm testing Weiawaga and it seems it has a rating around 2550 .. what do you think ? it's not mentioned in the CCRL lists.

i find it plays good moves : it has some own basic setup in the opening (playing 1.Nf3, 1.e4 and 1.d4) with an early e2-e3 and a sound strategy with lots of tactics .. i like its style! One flaw was in this endgame against Yace v0.99.50 (rating 2486) : 5bk1/6p1/5p1p/B2R4/8/r5P1/5PP1/6K1 w - - 0 36

White to move. It seems this is a draw but Weiawaga lost this game .. here's the PGN : Weiawaga_lost_against_Yace.zip

so Weiawaga needs to improve in the endgame ..

apart from that : well done ! Btw. it has no version number ?

I haven't started versioning yet, but plan to in the future (most likely after implementing multithreading). Probably I'll put it on CCRL at that point. This repository is still a bit of a work in progress after porting from a previous Java engine (https://github.com/Heiaha/WeiawagaJ), which I never put on CCRL because it was just using a hash map for the transposition table at that time and wasn't limiting its size, which wouldn't have been acceptable for CCRL.

Thanks for testing it out!

OK. What rating does it have ? What's your guess ? And do you admit it lacks some endgame skills ? It's a pitty that game was lost .. it seems Weiawaga was pushing too hard ..
