WebThe feasopt example demonstrates another approach to relaxing an infeasible model. It computes a feasibility relaxation for the infeasible model. A feasibility relaxation is a model that, when solved, minimizes the amount by which the solution violates the bounds and linear constraints of the original model. WebI had tested it on 2 sample infeasible problems (i.e. knew aprior as to which constraint are causing infeasibility) and found the hypothesis holds. I had taken a quick look at Cvxpy to Mosek conversion code in cvxpy codebase and found cvxpy doesn't change constraint ordering. So, the conclusion is the hypothesis.
