Constrained Multi-Objective Optimization

UCI Training Bounds Enforced

Searches strictly within the validated UCI training-data bounds. Enforces w/c = water / cement and w/b = water / (cement + slag + fly ash) separately, and verifies the returned mix against all constraints before marking it optimal.
