Rigorous global optimization

Comparison of Global Solvers
Within the COCONUT project, we performed extensive tests of the global solvers BARON, GlobSol, ICOS, LGO, LINGO, OQNLP, Premium Solver, MINOS, and COCOS (the solver in the alpha test version of the COCONUT environment) for various sublibraries of the COCONUT benchmark.


Derivative-free optimization heuristics

Comparison of derivative-free optimization algorithms (2012, by Nick Sahinidis)

Black-Box Optimization Benchmarking (BBOB) 2013 (by Auger, Hansen, et al.)

Competition on Large Scale Global Optimization 2013 (by Xiaodong Li)


A Comparison of Stochastic Global Optimization Programs in Fortran or C on 45 bound-constrained problems of dimension 2-30 (by Erich Janka)
Of the programs tested, the Derivative-Free Boender-Timmer-Rinnoy Kan Algorithm by Tibor Csendes is the clear winner. (But MCS and DIRECT/gblSolve that are publicly available in Matlab only and did not fit the environment of the above study are even better, at least on the more limited Dixon-Szego test set.)

W. Huyer, A comparison of some algorithms for bound constrained global optimization, Manuscript (2004). (pdf file, 69K)
The paper contains comparisons of the three heuristic global optimization programs MCS, Global, PGSL, using black box function evaluation only.

The Ph.D. thesis of Tom Epperly contains problem definitions and solutions (ps.gz, 59K) for constrained global optimization problems (among others from the Pardalos-Rosen test collection) together with test results for his branch and bound algorithm.
