◆ objective_degradation_absolute_tolerance

std::optional<double> operations_research::math_opt::ModelSolveParameters::ObjectiveParameters::objective_degradation_absolute_tolerance

Optional objective degradation absolute tolerance. For a hierarchical multi-objective solver, each objective fⁱ is processed in priority order: the solver determines the optimal objective value Γⁱ, if it exists, subject to all constraints in the model and the additional constraints that fᵏ(x) = Γᵏ (within tolerances) for each k < i. If set, a solution is considered to be "within tolerances" for this objective fᵏ if |fᵏ(x) - Γᵏ| ≤ objective_degradation_absolute_tolerance.

See also objective_degradation_relative_tolerance; if both parameters are set for a given objective, the solver need only satisfy one to be considered "within tolerances".

If set, must be nonnegative.
