Abstract

For more then twenty years we have been providing information on optimization software. This includes in particular performance evaluations over a wide range of problems and for both commercial and non-commercial software. Of the commercial products mainly CPLEX, Gurobi, and XPRESS are benchmarked on our own problem selections or instance libraries when available. This effort informs the public about the state-of-the-art and pushes the developers to improve their codes. While this went smoothly for many years, in late 2018 an event changed the situation substantially. The development will be chronicled and in addition to the presented history, a story will be told about the recent episode and how it affects the future.
