function Calculate ​

cpp
double Calculate(
    const std::vector< int > & cut_set,
    const Pdag::IndexMap< double > & p_vars
)

Calculates a probability of a cut set, whose members are in AND relationship with each other.

Parameters:

  • cut_set A cut set with positive indices of basic events.
  • p_vars Probabilities of events mapped by the variable indices.

Return:

  • The total probability of the cut set.
  • 1 for an empty cut set indicating the base set.

Precondition:

  • The cut set doesn't contain complements.
  • Probability values are non-negative.
  • Indices of events directly map to vector indices.

This function assumes independence of each member.
