add ESAs GTOP benchmarks #48

Closed dietmarwo closed 4 years ago

dietmarwo commented 4 years ago

This PR adds real world benchmark examples from https://www.esa.int/gsp/ACT/projects/gtop/ . Testing with these can further test/improve the algorithms. One issue with HHO - handling of lists as bounds - is already fixed in this PR. Beside that I noticed exceptions with GA, which I locally fixed by catching these, but it would be better if the root cause would be analyzed and fixed. A new dependency - fcmaes - is required because these benchmarks are implemented there.

My testing revealed clipping issues (boundary violations) for some of the algorithms - for HHO I already provided a PR related to this. The underlying GTOP C-code will log warnings about "negative flight time" which cannot be suppressed if the bounds are violated. Some links with GTOP-results for multi-threaded algorithms: http://www.midaco-solver.com/index.php/about/benchmarks/gtopx (there is also an alternative python wrapper) and https://github.com/dietmarwo/fast-cma-es/blob/master/Results.adoc . Midaco and fcmaes are the only optimizers I know which can solve all of these problems. The Midaco team writes: "Therefore researchers should not be discouraged if struggling to solve these benchmarks. Instead, the GTOPX library aims at senior researchers wishing to put advanced algorithms to the test."
