Function Documentation

void SgUctTreeUtil::ExtractSubtree	(	const SgUctTree &	tree,
		SgUctTree &	target,
		const std::vector< SgMove > &	sequence,
		bool	warnTruncate,
		double	maxTime = std::numeric_limits<double>::max(),
		SgUctValue	minCount = 0
	)

Extract the subtree from the node after a sequence of moves.

The result is an empty tree, if the sequence of moves does not correspond to a sequence of nodes from the root node in the given tree.

Parameters:

	tree	The source tree.
[out]	target	The target tree (will be cleared before using it).
	sequence	The sequence of moves.
	warnTruncate	See SgUctTree::ExtractSubtree
	maxTime	See SgUctTree::ExtractSubtree
	minCount

const SgUctNode * SgUctTreeUtil::FindChildWithMove	(	const SgUctTree &	tree,
		const SgUctNode &	node,
		SgMove	move
	)

Find move node with a given move.

Returns:

The child node or 0, if the position node has no such child.
