Cbc (Coin-or branch and cut) is an open-source mixed integer linear programming (MILP) solver written in C++. It can be used as a callable library or a stand-alone executable and integrates with many modeling systems such as AMPL, PuLP, JuMP, and OR-Tools.

Use cases

• solve mixed integer linear programming problems
• solve linear programming models from Python with PuLP
• use a MILP solver as a callable C++ library
• run an open-source alternative to commercial MIP solvers like Gurobi or CPLEX
• solve optimization models written in AMPL or MiniZinc
• integrate branch-and-cut optimization into an application

When to choose

• you need a free, open-source MILP/LP solver
• you want broad integration with modeling languages like AMPL, JuMP, PuLP, or OR-Tools
• you need both a command-line executable and an embeddable C++ library

When to avoid

• you need state-of-the-art performance on very large or hard MIP instances where commercial solvers excel
• you need constraint programming or nonlinear optimization rather than linear/integer programming
