class chmengine.engines.cmhmey2_pool_executor.CMHMEngine2PoolExecutor(board: Optional[Board] = None, depth: int = 1, max_workers: Optional[int] = None, time_limit: Optional[float64] = None)

Bases: object

cache_dir: str = '.\\SQLite3Caches\\QTables'

engine: CMHMEngine2

executor: ProcessPoolExecutor

pick_move(debug: bool = False) → Pick

Select the best move using conditional multithreaded evaluations.

Parameters:

debugbool, default: False

If True, prints debug information about the evaluations.

Returns:

Pick

The best move and its associated evaluation score.

push(move: Move) → None

Helper method to update the internal board state with a pushed move.

Parameters:

moveMove

shutdown() → None

Shut down the ProcessPoolExecutor.

chmengine.engines.cmhmey2_pool_executor.evaluate_move(board: Board, depth: int = 1, debug: bool = False, cache_dir: str = '.\\SQLite3Caches\\QTables') → Pick

Offloads eval calculations to another CMHMEngine2 instance.

Parameters:

boardBoard

The chess board state to evaluate.

depthint

The search depth for the evaluation.

debugbool

Whether to enable debug output.

cache_dirstr

The cache directory for the engine.

Returns:

Pick

The best move and its associated evaluation score.

Raises:

OperationalError

If the database remains locked after exhausting retries or for unexpected operational errors.
