13 May 2011 INTSOLVER: An interval based solver for Global Optimization Interval based functions to solve small global optimization problems with guaranteed bounds. Author: Tiago Montanher

free (even for commercial usage) solver interalg (http://openopt.org/interalg) seems to work tens-hundreds-thousands times faster and is more stable, the bench is provided there.

05 Apr 2009 fminconset Solves constrained minimization problems, some of the variables are restricted to discrete values Author: Ingar Solberg

you could compare it with translation of the routine to Python, see http://openopt.org/MINLP for details.

It's very hard to understand. Too many files and no comment

Is there further documentation available?

hi all,
I should inform you: some months ago OpenOpt had migrated to Python programming language, and no support and further development for MATLAB/Octave version will be provided.
Thanks all for your comments.

Works like a charm. However, I have a few remarks to improve the package. All suggested methods are available on Matlab Central:
1-a simplex method equivalent to fminsearch would be appreciated, suggesting the State Machine Simplex Minimizer.
2-a Levenberg Marquardt method would also be appreciated, e.g. LMFsolve.
3- a Genetic Algorithm method without constrains would also be nice, especially as GA is provided with the GAconstrain method. The gaevolv could also be good.
4- the powell method seems quite efficient and could be in OpenOpt
5- There are other swam optimizers, such as 'swarm' and 'PSO'. Are they slower/less efficient that the hPSO ?
Finally, thanks for this package. Probably a better documentation would be nice, e.g. regarding the many options in ooAssign, which depend on packages.
