double Calculate(
    const Zbdd & cut_sets,
    const Pdag::IndexMap< double > & p_vars
)

Calculates probabilities using the Rare-Event approximation.

Parameters:

  • cut_sets A collection of sets of indices of basic events.
  • p_vars Probabilities of events mapped by the variable indices.

Return: The total probability with the rare-event approximation.

Postcondition: In case the calculated probability exceeds 1, the probability is adjusted to 1. It is very unwise to use the rare-event approximation with large probability values.
