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: or NETLIB:


TOMS454 is available in a FORTRAN77 version.
