OR-Tools
Google's optimization toolkit for scheduling, routing and assignment.
OR-Tools bundles the CP-SAT constraint-programming solver (scheduling, assignment), linear and mixed-integer programming, and a dedicated vehicle-routing library. Available for Python, C++, Java and .NET, it's our choice when a business problem is best expressed as constraints and an objective to optimize rather than as a predictive model.
What OR-Tools brings to your project.
Typical use cases: Delivery routes, staff rosters, resource assignment, scheduling.
- 01
CP-SAT: a leading constraint solver, optimal or bounded solutions.
- 02
Linear and mixed-integer programming with GLOP, SCIP and third-party solvers.
- 03
Vehicle routing: time windows, capacities, heterogeneous fleets.
- 04
Open source (Apache 2.0), Python, C++, Java and .NET APIs.
