OR-Tools was created by Laurent Perron in 2011.
In 2014, Google's open source linear programming solver, GLOP, was released as part of OR-Tools.
The CP-SAT solver bundled with OR-Tools won a total of eleven gold medals between 2018 and 2020 in the MiniZinc Challenge, an international constraint programming competition.
The OR-Tools supports a variety of programming languages, including:
OR-Tools supports a wide range of problem types, among them:
It supports the FlatZinc modeling language.
