Detailed Description

ObservationHistory represents an action history of a single agent.

It does so by storing an index and a pointer to a preceeding observation history.

Constructor & Destructor Documentation

ObservationHistory::ObservationHistory	(	PlanningUnitMADPDiscrete &	pu,
		Index	agentI
	)
