Google OR-Tools is a free and open-source software suite developed by Google for solving linear programming (LP), mixed integer programming (MIP), constraint programming (CP), vehicle routing (VRP), and related optimization problems.[3][4]
OR-Tools is a set of components written in C++ but provides wrappers for Java, .NET and Python.
It is distributed under the Apache License 2.0.[5]
OR-Tools was created by Laurent Perron in 2011.[6]
In 2014, Google's open source linear programming solver, GLOP, was released as part of OR-Tools.[1]
The CP-SAT solver[7] bundled with OR-Tools won a total of eleven gold medals between 2018 and 2020 in the MiniZinc Challenge,[8] an international constraint programming competition.
The OR-Tools supports a variety of programming languages, including:
OR-Tools supports a wide range of problem types,[13][3] among them:
It supports the FlatZinc modeling language.[18]
