Worst-Case Feasibility for Alternatives Discovered by Search
Abstract
Constrained partition search and a worst-case formulation combine discovery risk with scenario-dependent admissibility. Evaluation should identify both missed regions and false acceptance among discovered candidates. The protected input description needs a substantive scale. Independent final checks assess the selected action under that description, without turning a nominal search peak into a universal feasibility guarantee. This focused synthesis develops an empirical comparison that preserves the terminal action, observation process, and total verification cost. Its proposed tests are prospective; no new simulation run, model-training result, or intervention effect is reported.
