Class ProbabilityResult

  • All Implemented Interfaces:
    
public class ProbabilityResult

    Result class for probability calculations in solvers.

    Supports both scalar probabilities (single value) and probability distributions (vectors/matrices) for marginal and aggregated state probabilities.

    For marginal probabilities (getProbMarg), the probability vector contains P(n jobs of class r) for n=0,1,...,N where N is the population.

    For aggregated probabilities (getProbAggr), the probability is a scalar representing P(n1 jobs of class 1, n2 jobs of class 2, ...).
