Equivalent function NCONF/NLQPL

hello folks!

I am looking for an equivalent function to NCONF/DNCONF which has been defined in the IMSL library. Here is the description of this function:

Solve a general nonlinear programming problem using the successive quadratic programming algorithm and a finite difference gradient.

Call NCONF (FCN, M, ME, N, XGUESS, IBTYPE, XLB, XUB, XSCALE, IPRINT, MAXITN, X, FVALUE)

In nutshell, I have to minimize a multi-variable function knowing that one (or more) condition have to be accomplished.

Thank you in advance.

The currently available subroutine in IMSL with the same functionality is NNLPF. The argument list and the interface for the user-supplied function subroutines are, of course, slightly different.

The current (updated) versions of NLPQLP may be obtained from the author, Professor Schittkowski, at http://www.ai7.uni-bayreuth.de/nlpqlp.htm.

If your problem involves mininizing the sum of squares of a set of functions with, at most, linear constraints, look at TRNLSPBC in MKL.

YES, I found it. Unfortunately, I have to deal with non linear constraints...

I'm moving this to the MKL forum.
