Hi

I wanted to know how to obtain same answer each time we run program of pattern search which has options of Search method "GPSPositiveBasis2n" and poll method of MADSPostiveBasis2N.

Thanks

A necessary condition for this (it may not be sufficient, I haven't checked)
is to reset the random number generator before each time you run your
patternsearch program. If you're using a version of MATLAB that uses
RandStream objects for random number generation (release R2008b or later)
then this is the syntax to use:

reset(RandStream.getDefaultStream);
