Class SimpleNode<P extends IGamePosition<P>>

java.lang.Object

gametree.GameTreeNode<SimpleNode<P>, P>

test.SimpleNode<P>

Type Parameters:

P - some implementation of IGamePosition which corresponds to the game being searched by this tree.

All Implemented Interfaces:

Serializable

public class SimpleNode<P extends IGamePosition<P>>
extends GameTreeNode<SimpleNode<P>, P>

Implementation of GameTreeNode that only acts as a facade for the underlying tree expressed by the P implementation of IGamePosition. No values are saved beyond the direct parental line of ancestors of each node and the depth of each node.

Method Details

_children

public List<SimpleNode<P>> _children(MetricKeeper... metrics)

Description copied from class: GameTreeNode

Method to implement functionality of GameTreeNode.children(MetricKeeper...).

Specified by:

_children in class GameTreeNode<SimpleNode<P extends IGamePosition<P>>, P extends IGamePosition<P>>

savedChildren

public Optional<List<SimpleNode<P>>> savedChildren()

Specified by:

savedChildren in class GameTreeNode<SimpleNode<P extends IGamePosition<P>>, P extends IGamePosition<P>>

Returns:

An Optional containing all children nodes saved in the memory of this GameTreeNode or an empty Optional if none are saved in memory. An Optional containing an empty List signifies a terminal node with no children.

_upperbound

public double _upperbound(MetricKeeper... metrics)

Description copied from class: GameTreeNode

Method to implement functionality of GameTreeNode.upperbound(MetricKeeper...).

Specified by:

_upperbound in class GameTreeNode<SimpleNode<P extends IGamePosition<P>>, P extends IGamePosition<P>>

_lowerbound

public double _lowerbound(MetricKeeper... metrics)

Description copied from class: GameTreeNode

Method to implement functionality of GameTreeNode.lowerbound(MetricKeeper...).

Specified by:

_lowerbound in class GameTreeNode<SimpleNode<P extends IGamePosition<P>>, P extends IGamePosition<P>>

hasSavedBounds

public boolean hasSavedBounds()

Specified by:

hasSavedBounds in class GameTreeNode<SimpleNode<P extends IGamePosition<P>>, P extends IGamePosition<P>>

maximising

public boolean maximising()

Description copied from class: GameTreeNode

This is IGamePosition.maximising() from the GameTreeNode.position() of this node.

Specified by:

maximising in class GameTreeNode<SimpleNode<P extends IGamePosition<P>>, P extends IGamePosition<P>>

Returns:

true if the current player-to-move is maximising the score, or false if it is minimising the score.

_adjustBounds

public boolean _adjustBounds(List<SimpleNode<P>> children,
 MetricKeeper... metrics)

Description copied from class: GameTreeNode

Method to implement functionality of GameTreeNode.adjustBounds(List<N>, MetricKeeper...).

Specified by:

_depthOfUpper

public long _depthOfUpper(MetricKeeper... metrics)

Description copied from class: GameTreeNode

Method to implement functionality of GameTreeNode.depthOfUpper(MetricKeeper...).

Specified by:

_depthOfUpper in class GameTreeNode<SimpleNode<P extends IGamePosition<P>>, P extends IGamePosition<P>>

_depthOfLower

public long _depthOfLower(MetricKeeper... metrics)

Description copied from class: GameTreeNode

Method to implement functionality of GameTreeNode.depthOfLower(MetricKeeper...).

Specified by:
