	)

protected

Constructor that only creates a BG of specified dimensions.

This constructor does not initialize the BG. This is useful when there are additional computations that have to be done. E.g., when this is a clusterable BG (BayesianGameWithClusterInfo), the types do not correspond in a straigtforward manner to action-observ. histories and therefore the probs. and payoff function have to be computed at this higher level.

		const QFunctionJAOHInterface *	q,
		const boost::shared_ptr< const PartialJointPolicyDiscretePure > &	pastJPol
	)

Constructor that creates and initializes a BG from scratch.

This constructor creates and initializes a BG for the next stage given the past policy and q function.

Extends a previous policy jpolPrevTs to the next stage.

This function extends a previous policy jpolPrevTs for ts-1 with the behavior specified by the policy of the BayesianGame for time step ts (jpolBG). jpolPrevTs - a joint policy for the DecPOMDP up to time step ts-1 (i.e. with depth=ts-2) jpolBG - a joint policy for the BayesianGame for time step ts. nrOHts - a vector that specifies the number of observation histories for eac agents at time step ts. firstOHtsI - a vector that specifies the index of the first time step ts observation history for each agent (this functions as the offset in the conversion BG->DecPOMDP index conversion).

returns a new JointPolicyDiscretePure (so it must be explicitly deleted)
