Chess Engine: Altair 2.0.0
Altair is a uci chess engine that succeeds my old python engine Antares.
Rating CEDR=2496 author: Alexander Tian
v.2.0.0:
This is the second version of Altair. There have been around 150-180 ELO rating gains from changes in its search, and the rest 250+ have been from tuning the evaluation and new evaluation features.
A huge thanks to Gedas, as many of the rating gains are the result of tuning using his texel tuner.
