optimization using Particle swarm optimization

Variables                     Levels 
  -1  0  1
Feed(mm/rev)  0.1  0.2  0.3
DOC(mm)  0.2  0.3  0.4
RPM  500  1250  2000
Tool wear= 0.0076390+ 0.000024*FEED+ 0.001581*RPM+ 0.000422*DEPTH OF CUT+ 0.000389*     FEED*FEED + 0.000663*RPM*RPM - 0.000849*FEED*RPM - 0.000749*FEED*DEPTH OF CUT + 0.000704*RPM*DEPTH OF CUT

Please be more specific about "it doesn't work" for your difficulties in installing the PSO toolbox.

Why bother?

feeds = [0.1 0.2 0.3];
docs = [0.2 0.3 0.4];
rpms = [500 1250 2000];

[FEED, DEPTH_OF_CUT, RPM] = ndgrid(feeds, docs, rpms);

Tool_wear = 0.0076390 + 0.000024 * FEED + 0.001581 * RPM + 0.000422 * DEPTH_OF_CUT + 0.000389 * FEED .* FEED + 0.000663 * RPM .* RPM - 0.000849 * FEED .* RPM - 0.000749 * FEED .* DEPTH_OF_CUT + 0.000704 * RPM .* DEPTH_OF_CUT;

[minwear, idx] = min(Tool_wear(:));

fprintf('Minimum wear %g at Feed %g DOC %g RPM %g\n', minwear, FEED(idx), DEPTH_OF_CUT(idx), RPM(idx));

I have also got somewhat similar type of prob in which i have to minimise surface roughness on the basis of certain parameters. If anyone has pso program for it plz mail me at [e-mail]

Thanks
