Benchmarks for Optimization Software

By Hans Mittelmann (mittelmann at asu.edu)


END OF A BENCHMARKING ERA
 For many years our benchmarking effort had included the solvers CPLEX, Gurobi, and XPRESS. Through an action by Gurobi at the 2018 INFORMS Annual Meeting this has come to an end. IBM and FICO demanded that results for their solvers be removed and then we decided to temporarily remove those of Gurobi as well. CPLEX was in fifteen of the benchmarks, Gurobi and XPRESS in thirteen. See here for more details. In late November 2019 selected benchmarks for Gurobi were added.
A partial record of previous benchmarks can be obtained from this webpage and some additional older benchmarks

Note that on top of the benchmarks a link to logfiles is given!

Note also that we do not use performance profiles. See this paper and that one

We use instead the shifted geometric mean
