CBC needs a LP solver and relies on the COIN Open Solver Inteface (OSI) to communicate with the user's choice of solver. Any LP solver with an OSI interface can be used with CBC. The LP solver expected to be used most commonly is COIN's native linear program solver, CLP. For cut generators, CBC relies on the COIN Cut Generation Library (CGL). Use the builds from coin-or/pulp, another modelling-tool for python (tested and works for me) Compile from source using mingw64 (Use any build and provide some external dll of zlib and co -> hard to debug) Of course i completely ignored other potential issues: license-stuff (what's part of those builds) I would like to code some IP/MIP models in python and test them with an open-source solver. As of now, I only know the Cbc - COIN-OR open-source solver.. I have already tried the or-tools interface, unfortunately, its capabilities are restricted (e.g., linear expressions are not possible).

The recommended open-source solver is Cbc (Coin-or branch and cut). Next, set the system’s PATH variable to include directories that include python components and packages. To do this go to My Computer -> Properties -> Advanced System Settings -> Environment Variables. In the User Variables section, edit or create the PATH statement to

pivot rules in the Python scripting language without explicitly interact-ing with the underlying C++ layers of CLP. In the same manner, it allows users to customize the solution process while solving mixed-integer linear programs using the CBC and CGL COIN-OR packages.

There is no maintainer for this port. The coins you have are of value 1, 2, 5, 10, 20, 50 and 100. Input: The input consists of a single line that contains the goal sum S. Output: Output the number of ways this sum could be build using coins of any value amongst 1, 2, 5, 10, 20, 50 and 100. You could use as many coins as you want from any value.

CyLP is a Python interface to COIN-OR’s Linear and mixed-integer program solvers (CLP, CBC, and CGL). CyLP’s unique feature is that you can use it to alter the solution process of the solvers from within Python. For example, you may define cut generators, branch-and-bound strategies, and primal/dual Simplex pivot rules completely in Python.
