◆ moves()

osl::book::WeightedBook::WMoveContainer osl::book::WeightedBook::moves	(	int	stateIndex,
		const bool	zero_include = true )

Return moves from the state of the stateIndex.

If the zero_include is true, all of the moves are returned. Otherwise, the moves that have some weights (i.e. non-zero value) are returned.

◆ parents()

std::vector< int > osl::book::WeightedBook::parents ( const int stateIndex )

As traversing the 'tree', return all state indices of the state's parents.

Returns: state indexes; empty if there is none.

◆ stateIndex() [1/2]

int osl::book::WeightedBook::stateIndex	(	const SimpleState &	state,
		const bool	visit_zero = true,
		const Player	player = BLACK )

As traversing the 'tree', find a state index of the state.

If the visit_zero is true zero-weighted moves are visited (in this case, player is ignored). Otherwise, the palyer's zero-weighted moves are not visited.
