Bases: qiskit.aqua.components.uncertainty_problems.uncertainty_problem.UncertaintyProblem

Multivariate Uncertainty Problem.

Constructor.

Parameters

uncertainty_model (MultivariateDistribution) – multivariate uncertainty model
aggregation_function (CircuitFactory) – aggregation function that maps the multiple dimension to an aggregated value
univariate_objective (UnivariatePiecewiseLinearObjective) – objective function applied to the aggregated value
conditions (Union[List[Tuple[int, CircuitFactory]], ndarray, None]) – list of pairs (int, CircuitFactory) = target dimension of uncertainty model and condition to be satisfied to apply the aggregation
