11 Oct 2022 long time no see 3 am well, there's a lot of small and big changes. i'll try to explain by checking the diff. AI part: replaced minimax with alpha-beta (similar to negamax version) TODO : implement quiescence search added piece-square table scoring in eval function reduced branching in code move generation part: bugfix : moves like e1c1 were always interpreted as castling, fixed changed board representation from string to char[64] now king positions are incrementally saved, so faster to find kings several optimizations in move generation general: now engine trys to avoid moves leading to repetitions (but it is not always optimal, so should do something better) fixed several gui bugs in promotion and flipping gui supports (some) premoves fixed some bugs in move hints, still some remaining ig faster makefile BIGGEST UPDATES: uci protocol working! made a lichess bot running this engine!
