Detailed Description

Abstract interface for search algorithms.

This interface defines the standard lifecycle of a search algorithm, allowing the engine to switch between implementations (e.g., Negamax vs. MCTS).

Member Function Documentation

getNodes()

virtual uint64_t ISearch::getNodes ( ) const

pure virtual

Retrieves the total number of nodes evaluated by the search algorithm.

Returns

The node count.

Implemented in MCTS, and Negamax.

isSearching()

virtual bool ISearch::isSearching ( ) const

pure virtual

Checks if the search algorithm is currently running.

Returns

True if a search is in progress.

Implemented in MCTS, and Negamax.

setInfoCallback()

virtual void ISearch::setInfoCallback ( InfoCallback callback )

pure virtual

Sets the callback function for periodic information updates.

Parameters

callback

The function to call with depth, score, node count, NPS, and PV.

Implemented in MCTS, and Negamax.

startSearch()

virtual Move ISearch::startSearch ( Board & root, const SearchParams & params )

pure virtual

Starts the search process on the given root board.

This is a blocking call that will execute the search algorithm until the stopping conditions in params (or stop()) are met.

Parameters

root	The starting board position.
params	The time and depth constraints for the search.

Returns

The best move found.

Implemented in MCTS, and Negamax.

stop()

virtual void ISearch::stop ( )

pure virtual

Asynchronously signals the search to stop immediately.

This method must be thread-safe.

Implemented in MCTS, and Negamax.
