ABACUS is a software system which provides a framework for the implementation of branch-and-bound algorithms using linear programming relaxations that can be complemented with the dynamic generation of cutting planes or columns (branch-and-cut, branch-and-price,branch-and-cut-and-price).

Software for linear, integer and nonlinear optimization. LINDO supplies large scale solvers with links to Excel and database applications.

The CPLEX division of ILOG provides large-scale mathematical programming software and services for resource optimization.

Modular program for solving nonlinear least-square parameter estimation problems. Provides instructions how to port two important optimization Fortran codes to C.

Software, benchmarks, events, people, bibliography, quadratic optimization.

Dash Optimization: for Linear, Integer and Quadratic Programming and Optimization Modeling.

Matlab, C, and Fortran codes to minimize nonlinear, possibly non-smooth objective functions and solve nonlinear minimization problems, taking into account constraints by the method of exact penalization.
