A Python interface to CLP, CBC, and CGL to solve LPs and MIPs.
On my home computer, I have Windows 10. I can install cylp by simply running pip install cylp I tried to do the same in GitHub actions, in a Windows...
I am using this example: http://coin-or.github.io/CyLP/modules/CyCbcModel.html On jupyter kernel dies at `cbcModel = s.getCbcModel()` Ipython displays this error `/home/builder/.termux-build/coinor-clp/src/src/OsiClp/OsiClpSolverInterface.cpp:7183: virtual int OsiClpSolverInterface::dualPivotResult(int &, int &, int, int, double &, CoinPackedVector...
On current master (which has the fix for the memory leak: https://github.com/coin-or/CyLP/commit/72d66b58af5ac0cee25d94b63115c6f65e3cff8b ) I'm getting a segfault when running standard cylp tests (from the file `cylp/py/test_PySolve.py`). I've converted that test...
New to cylp, I install cylp by pip and run the file CyLP/cylp/tests/test_MIP.py But python returns with error: " cbcModel.branchAndBound() AttributeError: 'cylp.cy.CyCbcModel.CyCbcModel' object has no attribute 'branchAndBound' " I hope...
I have a simple question: in CyLP documentation, it says: Cbc. The version should be 2.10 (recommended) is that still the case or we can use 2.10.8 binary to build...
I would like to surpress all printing of the primal simplex solver for CyClpSimplex when calling primal(). I have tried to do so with python contextlib to redicrect stdout and...
## tldr I'm trying to add booleans together, hoping that the result is a boolean OR. I'm expecting a boolean OR, XOR, or an error, or `INFEASIBLE`. But what happens...
Hello, I use cvxpy with cbc solver from CyLP to solve ILP problem of a big size. Parameters which I pass to cvxpy function solve: `problem.solve(verbose=True, solver='CBC', numberThreads = 1,...
https://github.com/coin-or/Osi/blob/master/src/Osi/OsiSolverInterface.hpp has lots of useful methods, but https://github.com/coin-or/CyLP/blob/master/cylp/cy/CyOsiSolverInterface.pxd does not expose them.
CyLP wraps `ClpSimplex::getBInvACol` and `ClpSimplex::getBInvCol` but not `getBInvARow`, `getBInvRow` https://github.com/coin-or/Clp/blob/master/src/ClpSimplex.hpp#L1651
