		BGClusterAlgorithm	clusterAlg = `Lossless`
	)

Constructor used to construct a BayesianGameWithClusterInfo from scratch.

Given a past Dec-POMDP policy a new BG is constructed (not `bootstrapped' from a previous BG). This means that the resulting BG look exactly the same as when constructing a regular BayesianGameForDecPOMDPStage, only with the additional information about state probabilies (the joint beliefs) and types. Note that the type structure will contain for each agent a list with exactly 1 type for each history

store this type:

This constructor builds a BayesianGameWithClusterInfo from a BGWCI for the previous stage (i.e., using `bootstrapping').

Because we first need to compute the number of new types for each agent by extending the type-lists from prevBG, it is impracticle to call this constructor directly. Rather this constructor is called by ConstructExtendedBGWCI.

shifts all the probability mass from agent agI's type t2 to t1.

This function is used when clustering types t1 and t2. In particular, this function shifts the probability mass of all joint types involving t2 to the corresponding ones involving t1. E.g.: Let <t u>=""> denote a joint type, then this function performs: P( <t1 u> ) := P ( <t1 u>=""> ) + P( <t2 u > ) P( <t2 u> ) := 0

Note: when performing approximate clustering, this function should also average the utilities of the corresponding joint types.
