Mida v1.2 released
Posted: Tue Jul 18, 2023 1:09 pm
I'm happy to announce the release of Mida v1.2, which should be aruond 2350-2400. I thank Graham Banks and Gabor Szots for testing the previous version and making me realize it wasn't where I thought it was. I worked hard and introduced some novelties that should bring this version where I hoped.
I did some proper testing this time, and these are the results. Against v1.0, I played a 60 game match in 30+0,4 seconds format, with these outcome:
Score of v1.2 vs v1.0: 39 - 11 - 10 [0.733]
... v1.2 playing White: 20 - 6 - 4 [0.733] 30
... v1.2 playing Black: 19 - 5 - 6 [0.733] 30
... White vs Black: 25 - 25 - 10 [0.500] 60
Elo difference: 175.7 +/- 91.4, LOS: 100.0 %, DrawRatio: 16.7 %
60 of 60 games finished.
Just to make sure, I also played some games against Hopper, an engine on that 2350-2400 ELO range in CCRL blitz, and the results were pretty drawish, confirming my hyptothesis, therefore I stopped the testing early . I stoppped the testing at 43 games with these results
Score of v1.2 vs Hopper: 15 - 15 - 11 [0.500]
... v1.2 playing White: 10 - 8 - 3 [0.548] 21
... v1.2 playing Black: 5 - 7 - 8 [0.450] 20
... White vs Black: 17 - 13 - 11 [0.549] 41
Elo difference: 0.0 +/- 93.0, LOS: 50.0 %, DrawRatio: 26.8 %
43 of 100 games finished.
