get_argmax_sum_violations

(function from pyomo.contrib.pyros.separation_problem_methods)

pyomo.contrib.pyros.separation_problem_methods.get_argmax_sum_violations(solver_call_results_map, ss_ineq_cons_to_evaluate)

Get key of entry of solver_call_results_map which contains separation problem solution with maximal sum of second-stage inequality constraint violations over a specified sequence of second-stage inequality constraints.

Parameters:

• solver_call_results (ComponentMap) – Mapping from second-stage inequality constraints to corresponding separation solver call results.

• ss_ineq_cons_to_evaluate (list of Constraints) – Second-stage inequality constraints to consider for evaluating maximal sum.

Returns:

worst_ss_ineq_con – Second-stage inequality constraint corresponding to solver call results object containing solution with maximal sum of violations across all second-stage inequality constraints. If found_violation attribute of all value entries of solver_call_results_map is False, then None is returned, as this means none of the second-stage inequality constraints were found to be violated.

Return type:

None or Constraint
