CBC
CBC (Coin-or branch and cut) is an open-source mixed-integer linear programming (MILP) solver developed as part of the COIN-OR (Computational Infrastructure for Operations Research) project. It uses branch-and-bound and cutting-plane algorithms to find optimal solutions for optimization problems with integer variables, linear constraints, and a linear objective function. It is widely used in operations research, logistics, scheduling, and resource allocation applications.
Developers should learn CBC when working on optimization problems that involve discrete decisions, such as production planning, network design, or vehicle routing, where variables must take integer values. It is particularly valuable in academic, research, or cost-sensitive industrial settings due to its open-source nature and integration with modeling languages like PuLP or Pyomo, offering a free alternative to commercial solvers like CPLEX or Gurobi.
