COIN-OR Foundation's Projects
A Python interface to CLP, CBC, and CGL to solve LPs and MIPs.
DIP is a decomposition-based solver framework for mixed integer linear programs.
This a mirror of the subversion repository on COIN-OR.
Discrete Conic Optimization Solver
A Templatized C++ Framework with Python Bindings for Heuristic Search
Dynamic Simplex solver
a library for nonlinear optimization written in Fortran
An open source algebraic modelling language implemented as a C++ class library
Links between GAMS (General Algebraic Modeling System) and solvers
A graph library containing pure Python implementations of a variety of graph algorithms
Mathematical Modeling for Optimization and Machine Learning
A Python library for visualizing algorithms for solving mathematical optimization problems.
A mirror of the HiGHS LP solver repository. Do not open pull-requests here.
COIN-OR Interior Point Optimizer IPOPT
Java framework for Markov-chain (MC) modelling
Java Operations Research Library
LaGO (Lagrangian Global Optimizer) is a software-package for the global optimization of nonconvex mixed-integer nonlinear programs (MINLP).
MC++ is a toolkit for bounding factorable functions. It provides methods for computing bounds on a factorable function in the form of convex/concave relaxations, Taylor models, and spectral bounds.
An Open Source Tabu Search Metaheuristic framework in C++
Examples for METSLib
A solver for mixed integer bilevel programs
Minotaur Toolkit for Mixed-Integer Nonlinear Optimization
Algorithms and heuristics to solve multicriteria matroid optimization problems
NLPAPI is a set of subroutines and data structures for defining nonlinear programming problems. It includes an interface to call LANCELOT to solve the problem (you need to get your own copy of LANCELOT), and an interface to IPOPT.
Overlapping Branch and Bound Algorithm
OBOE (Oracle Based Optimization Engine) is an open source software for general convex optimization.
