scripts default iconfminsearch2 (Scripts) Publisher's description

This is a (small) change to the current fminsearch routine to improve convergence.

This is a (small) change to the current fminsearch routine to improve convergence.

The current fminsearch selects n additional simplex points based on a small change in each variable. This implementation uses an adaptive procedure to select these n points while maintaining the correct relative distance to the centroid of the remaining points.

Changing these initial points gave 11% fewer runs and reached the correct solution 6% more on the test suite by More et al.

System Requirements:

MATLAB 7.4 (R2007a)
Program Release Status: New Release
Program Install Support: Install and Uninstall
