Optimization codes at Netlib.

Fortran 77 package for solving unconstrained and constrained optimization problems, systems of nonlinear equations, and nonlinear least-squares problems.

Minimizes the maximum of a set of smooth objective functions subject to general smooth constraints. Includes algorithm and problem descriptions, references, and pricing information. Free for academic use.

Fortran 90 code implementing the Differential Evolution method, a simple but powerful population-based, stochastic function minimizer.

Fortran 90 package for finding approximate solutions of certain binary quadratic programs, currently including the Max-Cut and the Max-Bisection problems.
