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 remove those of Gurobi as well. CPLEX was in fourteen of the benchmarks, Gurobi and XPRESS in twelve.
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!
