After modeling your problem in the programming language of your choice, you can use any of a half-dozen solvers to solve it: commercial solvers such as Gurobi or CPLEX, or open-source solvers such as SCIP, GLPK, or Google's GLOP and award-winning CP-SAT.
The suite contains:
A constraint programming solver;
A linear programming solver;
Wrappers around commercial and other Open Source solvers, including mixed integer solvers;
Bin packing and knapsack algorithms;
Algorithms for the Traveling Salesman Problem and Vehicle Routing Problem;
Graph algorithms (shortest paths, min cost flow, max flow, linear sum assignment).
Google wrote OR-Tools in C++, with provided wrappers for Python, C#, and Java.
