Detailed Description

StateとWMoveを保持する.

Stateはvector<WMove>を保持する WMoveはMoveとそのMoveを採用した時のStateのindexと手番から見た Moveの重み(0-1000)をもつ ファイル形式 version番号 - 4byte state数 - 4byte move数 - 4byte 開始state index - 4byte State - 16byte * state数

• WMoveの開始index
• WMoveの数
• 先手の勝数
• 後手の勝数 WMove - 12byte * WMove数
• Move (4byte)
• Stateのindex
• Weight CompactBoard形式の盤面 - 164byte * state数

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.

Definition at line 146 of file openingBook.cc.

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.

seek()

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.

Parameters

state	to find
visit_zero
player

Returns

a state index of the state; if it is not found, return -1.

Definition at line 241 of file openingBook.cc.

stateIndex() [2/2]

int osl::book::WeightedBook::stateIndex

(

const std::vector< Move > &

moves

)

As traversing the 'tree', find a state index of the state reached by applying the moves from the initial state.

Note that zero-weighted moves are visited.

Parameters

moves

to apply

Returns

state index; if it is not found, return -1.
