TOMS454
The Complex Method for Constrained Optimization

TOMS454 is a FORTRAN77 library which implements ACM TOMS algorithm 454, for the complex method of constrained optimization.

The text of many ACM TOMS algorithms is available online through ACM: http://www.acm.org/pubs/calgo or NETLIB: http://www.netlib.org/toms/index.html.

Languages:

TOMS454 is available in a FORTRAN77 version.

List of Routines:

• JCONSX finds the constrained maximum of a function of several variables.
• JCEK1 checks all points agains the explicit and implicit constraints.
• JCENT computes the centroid of a set of points.
