Detailed Description

JointActionHistory represents a joint action history.

This consists of a joint action history index, the last joint action (index) a pointer to the predecessor JOH. and a vector of indexes to the individual action histories.

Constructor & Destructor Documentation

JointActionHistory::JointActionHistory

(

PlanningUnitMADPDiscrete &

pu

)

Constructor - creates a new initial (=empty) JointActionHistory.

This method relies on the fact that the empty individual action histories are indexed 0.

References _m_individualActionHistories, _m_isEmpty, _m_jointActionI, _m_pred, PlanningUnitMADPDiscrete::GetNrAgents(), and History::SetLength().

Referenced by Clone().

JointActionHistory::JointActionHistory	(	PlanningUnitMADPDiscrete &	pu,
		Index	jObsI
	)

Creates a initial action history specifying obsI as the action at time step t=0 (o^t=0)

JointActionHistory::JointActionHistory	(	Index	jObsI,
		JointActionHistory *	pred
	)

Creates a action history specifying jObsI for the last joint action and pred as the preceeding JointActionHistory.

Index JointActionHistory::_m_jointActionI

private

The last joint action (index).
