    About OR-Tools
    OR-Tools is an open source software suite
    for optimization, tuned for tackling the world's toughest
    problems in vehicle routing, flows, integer and linear programming,
    and constraint programming.

    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.
