NettetCBC (COIN-OR branch and cut) is an open-source mixed integer programming solver (Forrest & Lougee-Heimer 2005). It is developed as part of the Computational Infrastructure for Operations Research (COIN-OR) project . By leveraging the CBC solver, this function can be used to generate solutions to optimization problems.

NettetSolver is a Microsoft Excel add-in program you can use for what-if analysis. Use Solver to find an optimal (maximum or minimum) value for a formula in one cell — called the objective cell — subject to …
NettetThe Relative Optimality Tolerance is a value r, ranging from 0 to 1, indicating to the branch-and-bound solver that it should only search for integer solutions with objective values at least 100* r % better than the best integer solution found so far.. The end results of modifying the search procedure in this way are twofold.
