Aug 7, 2020 at 6:41 comment added Richard I agree with @prubin: this falls into the category of solution quality. It is key that a solver is reliable and provides a high quality solution. This is why I find mathematical solvers so appealing, since the optimality gap gives an unambiguous metric for the quality.
Aug 6, 2020 at 18:04 comment added prubin I'd say it's more related to solution quality. With a heuristic, you don't expect an optimal solution each time, but you also don't want to judge it on the best of a series of runs. I would be inclined to judge it on median performance and also perhaps on the quartiles of performance, or the 10th and 90th percentiles, or some other measure of spread.
Aug 5, 2020 at 17:32 comment added Joffrey L. Okay so, here is a problem: If I run the solver 20 times with a heuristic approach, the best results are far from the median. Is this problem related to the robustness ?
