BOT Sturddle
No note yet
Sturddle is a multi-algorithm standard chess engine that uses MTD(f) by default but can be configured to use Negascout or plain Negamax, all within one search framework. The engine is a hybrid (like the sturddlefish) written in a mix of Python, Cython, and C++; periodically updated, and re-tuned using Chess Tuning Tools (chess-tuning-tools.readthedocs.io/en/latest/).
