Optimality tolerance
WebSets a relative tolerance on the gap between the best integer objective and the objective of the best node remaining. Purpose Relative MIP gap tolerance Description When the value bestbound-bestinteger / (1e-10+ bestinteger ) falls below the value of this parameter, the mixed integer optimization is stopped. WebThis tolerance is the number of seconds before the branch-and-bound solver begins using the relative optimality tolerance. For the first n seconds, where n is the value of the time to relative tolerance, the branch-and-bound solver will not use the relative optimality tolerance and will attempt to find the true optimal solution to the model.

WebMinimum found that satisfies the constraints. Optimization completed because the objective function is non-decreasing in feasible directions, to within the value of the optimality tolerance, and constraints are satisfied to within the value of the constraint tolerance. Elapsed time is 0.021717 seconds. WebOptimalityTolerance is a tolerance for the first-order optimality measure. If the optimality measure is less than OptimalityTolerance, the iterations end. OptimalityTolerance can also be a relative bound on the first-order optimality measure. See Tolerance Details. Tolerance Details. Optimization Toolbox™ solvers use tolerances to decide when to …

Web12 rows · Purpose Optimality tolerance Description Influences the reduced-cost tolerance … WebThe number of iterations in an optimization depends on a solver's stopping criteria. These criteria include several tolerances you can set. Generally, a tolerance is a threshold which, if crossed, stops the iterations of a solver. Set tolerances and other criteria using optimoptions as explained in Set and Change Options.
