for forumulating, solving and understanding optimization problems

abstract

AMPL is a language and system for formulating, solving, and
helping understand mathematical programming
problems (of minimizing or maximizing a function
subject to constraints).
A flexible interface enables several
solvers to be available at once and allows a user to switch between
solvers and to select options that may improve solver performance.
Once optimal solutions have been found, they are expressed in terms
of the modeler's notation so that they can be viewed and analyzed.
All of the general set and arithmetic expressions of AMPL can also
be used for displaying data and results; a variety of options are
available to format data for browsing on a screen, printing reports,
or preparing input to other programs.

Netlib has an AMPL area that contains bug reports, executables
compiled by Symantec and WATCOM, sample models, and sample
code that demonstrates how to interfaces optimization subroutines to
AMPL.
