Verifying a reported solution

The questions hand you a model and a report and ask which checks pass. Running the checks is quick; remembering to test against the model as you wrote it, rather than against the input the solver read, is what needs practice.

What this covers

  • Verify a reported solution against the model as written

    Given a model and a reported solution, a status, a point and an objective value, the learner can test primal feasibility against the original constraints, recompute the objective, judge whether the status is credible, and identify which class of fault a discrepancy indicates.
