Open Positions in Global Optimization
Bulgarian translation -- Belorussian translation
This is a comprehensive archive of online information on (almost exclusively non-commercial) global optimization, and somewhat less comprehensive on local optimization, collected by Arnold Neumaier on the web server http://www.mat.univie.ac.at/~neum/glopt.html of the Computational Mathematics group at the University of Vienna, Austria. Later on this page there is a Table of Contents of this Site.
Please help to keep the archive up to date by informing me at Arnold.Neumaier@univie.ac.at about new or missing electronic documents related to public domain work on global optimization, and about links that are no longer working.
Related, but not formally part of this site are two other sites maintained by our research group in Vienna:

Constrained global optimization (pdf, 225K), slides of a lecture (by Arnold Neumaier)
RSOLVER (by Stefan Ratschan)

projecting the solution set of a set of inequality constraints to two
dimensions.

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.
SNOBFIT, MATLAB 6 package for the robust and fast solution of optimization problems with continuous variables varying within bound, possibly subject to additional soft constraints
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 COCONUT environment is publicly available in an alpha test version since March 20, 2004.
Since starting this optimization page (September 1, 1995), this page was accessed steadily by about 30-40 different computers per day (last counted in 1999).
Updates to the contents are made quite frequently. I try to keep a complete coverage of public domain work on continuous global optimization; many references to combinatorial and local optimization are included for my (and your) convenience, but there I don't aim at completeness. Thanks to all who helped me by providing useful information.
The archive was reorganized on November 12, 1996; it now contains more than 1000 links to sources outside our server.
Please write me to Arnold.Neumaier@univie.ac.at if your own work is not referenced, if you know some other useful link to public domain work that is missing here, or if you find any invalid links.
If you do lots of computer work, prevent Computer Related Repetitive Strain Injuries by improving your typing habits.
