Available forms

CONOPT is available as an integrated or optional solver with many of the modern modeling systems and it is available as a Fortran Subroutine library.

We recommend that you always consider using CONOPT with a Modeling System. It is much easier and more reliable, especially during model development. Due to higher volume and lower support requirements the modeling system versions of CONOPT are also cheaper. Additional information on CONOPT for the various modeling systems is available directly from the vendors of these systems at the following addresses (given in alphabetical order):

The versions of CONOPT available with the modeling systems are all designed to follow the conventions of the modeling system and they are optimized for the particular model format of each modeling system. Most modeling systems and their CONOPT solver are available on a number of hardware platforms.
