int BeliefValue::GetMaximizingVectorIndex ( const JointBeliefInterface b,
const VectorSet v,
const std::vector< bool > &  mask 
)

Returns the index of the vector in v that maximizes the value of b.

If no vector has its mask enabled, the function returns -1.

Only vectors whose mask is true will be considered.
