A Python interface to CLP, CBC, and CGL to solve LPs and MIPs.
Build a wheel for linux on arm to enable e.g. dockerized usage on Apple Silicon an SBCs. closes [#158](https://github.com/coin-or/CyLP/issues/158)
CyCoinModel allocates a C++ object `CppSelf` and fails to deallocate it. A simple test script allocating `CyCoinModel` objects in a loop and deleting them shows significant memory leaked prior to...
It appears that the `s.variables[i].toInd` value is computed differently for the first variable created (i==0) than it is treated for variable created later. The indexing for the i=0 variable goes...
Hi, I added 4 new properties to CyCbcModel. Please consider merging the other PR https://github.com/coin-or/CyLP/pull/120 created by my colleague or let me know what we can do better =)
For improved performance, adding 2 new properties 1. **primalColumnSolution** as alternative to 'primalVariableSolution' 2. **dualColumnSolution** as alternative to 'dualVariableSolution' These 2 new properties allow solution data to be retrieved as...
I'm solving multiple LP problems stored in .mps files. Each problem has around 2000 variables and 1000 constraints, .mps file size is about 9 Mb. I've noticed that the memory...
From the code in `OSI`, I know that the artifical variable is defined as `lb
I'm trying to run the example ```python from cylp.cy import CyClpSimplex from cylp.py.pivots import DantzigPivot # Get the path to a sample mps file f = "cylp_/input/p0033.mps" s = CyClpSimplex()...
