[jira] Created: (MATH-353) Constrained version of the Nelder-Mead simplex method and bi-cubic interpolation

Constrained version of the Nelder-Mead simplex method and bi-cubic interpolation
--------------------------------------------------------------------------------

                 Key: MATH-353
                 URL: https://issues.apache.org/jira/browse/MATH-353
             Project: Commons Math
          Issue Type: Wish
            Reporter: Dimitri Pourbaix
            Priority: Minor


The library http://www.ee.ucl.ac.uk/~mflanaga/java/ offers a constrained version of the Nelder-Mead simplex method through the addition of a penalty function.  Such a possibility seems to be missing from commons-math.

The same library also offers some bi-cubic interpolation which is also absent in commons-math.

Phil Steitz updated MATH-353:
-----------------------------

    Affects Version/s: 2.1
                       2.0

Anyone interested in implementing this?  Should we move this to the wishlist?
