OR-Tools includes solvers for:

  • Constraint Programming - CP-SAT solver: A constraint programming solver that uses SAT (satisfiability) methods. - Original CP solver: A constraint programming solver.

  • Linear and Mixed-Integer Programming - Glop: A linear optimizer to find the optimal value of a linear objective function, given a set of linear inequalities as constraints. - MPSolver, ModelBuilder: Wrappers around commercial and other open source solvers, including mixed integer solvers: CBC, CLP, GLPK, Gurobi or SCIP.

  • Vehicle Routing A specialized library for identifying best vehicle routes given constraints.

  • Graph Algorithms Code for finding shortest paths in graphs, min-cost flows, max flows, and linear sum assignments.
