Detailed Description

Enhanced version of SGBaseAction.

Same functionality as SGBaseAction, but includes additional methods for computing payoffs and a reference to a parent SGEnv object to control parameters for the computation.

This class is used by the pencil sharpening algorithm and has been deprecated.

Constructor & Destructor Documentation

◆ SGAction_PencilSharpening() [1/2]

SGAction_PencilSharpening::SGAction_PencilSharpening ( const SGEnv & _env )

inline

Constructor.

Constructs a null action associated with the given SGEnv.

◆ SGAction_PencilSharpening() [2/2]

SGAction_PencilSharpening::SGAction_PencilSharpening	(	const SGEnv &	_env,
		int	_state,
		int	_action
	)

inline

Constructor.

Constructs an action for the given state and action index in the given environment.

Member Function Documentation

◆ calculateBindingContinuations()

void SGAction_PencilSharpening::calculateBindingContinuations	(	const vector< bool > &	updatedThreatTuple,
		const SGGame &	game,
		const vector< SGTuple > &	extremeTuples,
		const SGTuple &	threatTuple,
		const SGTuple &	pivot,
		const SGPoint &	currentDirection,
		int	oldWest
	)

Calculates binding continuation values.

This code is deprecated. Was part of the pencil sharpening algorithm.

◆ calculateMinIC()

double SGAction_PencilSharpening::calculateMinIC	(	int	action,
		int	state,
		int	player,
		const SGGame &	game,
		const SGTuple &	threatTuple
	)

static

Calculates the IC constraint.

Calculates the minimum incentive compatible expected continuation value for the given action, relative to the given threat tuple and for the given SGGame.

◆ intersectRay()

void SGAction_PencilSharpening::intersectRay	(	const SGPoint &	pivot,
		const SGPoint &	direction
	)

Trims binding continuation segments.

Intersects the binding continuation segments in SGAction::points with the half space that is below pivot in direction.getNormal().

◆ intersectRaySegment()

void SGAction_PencilSharpening::intersectRaySegment	(	const SGPoint &	pivot,
		const SGPoint &	direction,
		int	player
	)

Static method to carry out trimming operations.

Intersects the action with the ray emanating from pivot in the given direction.

Member Data Documentation

◆ env

const SGEnv& SGAction_PencilSharpening::env

private
