Galahad
Thread-safe library of Fortran 90 packages for solving nonlinear optimization problems, covering unconstrained and bound-constrained optimization, quadratic programming, nonlinear programming, systems of nonlinear equations and inequalities, and nonlinear least squares problems.
Genetic Algorithms
For use in designing composite materials, by Layne T. Watson.
Global Optimization
Links to global optimization code, mainly in Fortran 77 and C, but some links to local minimizers as well.
Global Solutions (GlobSol)
Package for rigorous solution of non-linear systems and global optimizations problems.
Klaus Schittkowski's Optimization Software
Nonlinear programming codes: SQP, least squares, multicriteria optimization, data fitting in ODEs, DAEs, PDEs, PDAEs.
Ladislav Luksan Optimization Code
Fortran 77 codes for nondifferentiable, large-scale, or dense nonlinear optimization.
Lancelot
Fortran 77 package for solving unconstrained and constrained optimization problems, systems of nonlinear equations, and nonlinear least-squares problems.
Linear Programming
Ratfor code for the primal-dual log barrier form of the interior point LP solver of Lustig, Marsten and Shanno, ORSA J Opt 1992.
Minpack
Fortran 77 code for solving nonlinear equations and nonlinear least squares problems. Five algorithmic paths each include a core subroutine and an easy-to-use driver. The algorithms proceed either from an analytic specification of the Jacobian matrix or directly from the problem functions.
Modulopt Optimization Routines
Fortran 77 codes for unconstrained, bound constrained, and nonlinearly constrained optimization.
Network Optimization Codes
By Dimitri P. Bertsekas.
Nonlinear Constrained Optimization
Solves online constrained optimization problems specified by the user as Fortran programs.
Opt
Optimization codes at Netlib.
Optimization Software Developed by J. Nocedal's Research Team
KNITRO, General Nonlinear Programming Solver; L-BFGS, Limited Memory Codes; PREQN, Preconditioning the Conjugate Gradient Method; and CG+, Conjugate Gradient Software.
Pikaiai
General-purpose optimization subroutine based on a genetic algorithm, in Fortran 90.
Projection-Type Methods for Large Quadratic Programs
Fortran 77 code by Valentia Ruggiero for large and sparse convex quadratic programs.
Quadratic Assignment Problem Library (QAPLIB)
By R.E. Burkard, E. Çela, S.E. Karisch and F. Rendl.
Stanford Business Software
Sells Fortran 77 optimization codes MINOS (linear programming and nonlinear optimization), SNOPT (large-scale quadratic and nonlinear programming), NPSOL (nonlinear programming), LSSOL (Linearly constrained linear least squares problems and convex quadratic programmmin), and QPOPT (linear and quadratic programming).
