Global and Non-smooth optimization toolbox

Matlab interface to GANSO library

Description

GANSO is a programming library for global and nonsmooth, nonlinear optimization. Unlike local methods (e.g., quasi-Newton), global optimization methods aim at locating the absolute minimum of a function, not the nearest stationary point. GANSO toolbox provides an interface for calling GANSO methods from Matlab. The user manual describes various optimization strategies, complete syntaxis and several examples of Matlab code.

• MATLAB release: MATLAB 6.5.1 (R13SP1)
• Other requirements: Requires a separate download of GANSO libraries from http://www.ganso.com.au/libs/GANSO_Matlab_libraries.zip

1) your free version of Ganso is restricted up to 100 variables, up to 100 constraints
elseware "error 200" is occured. You would better to inform Matlabcentral users about the restrictions before downloading the files.
2) ctrl-c doesn't work with your mex-funcs
3) both your your examples from documentation gansomatlab.pdf page 6 don't work ("incorrect number of variables")
4) despite all my vectors were N x 1 size, objFun gets 1 x N vector, which makes additional difficulties

Actually GANSO, has no support for nonlinear programming. One should modify the nonlinear functions to linear ones to make GANSO working. This is not feasible in most of the cases.

[Gleb Beliakov]

this is not true. Ganso does not support nonlinear constraints, which ns not the same what you stated, but works with nonlinear objective function. nonlinear constraints must be incorporated as penalty functions

How do I get GANSO to work with Matlab? I copied the dlls to the required directory but matlab is still unable to find the function. Any help in this regard will be greatly appreciated.

Thanks
