Python interface for the SCIP Optimization Suite
Using ```branchVar(v)``` will crash the code if ```v``` is not a scip variable. A simple fix for this is to change the definition in ```scip.pxi``` from ``` def branchVar(self, variable):...
At the time of writing, PySCIPOpt's test coverage is around $58.4\\%$. Increasing the test coverage is not too difficult and would improve the project. ### How to write a new...
I forgot to delete it, but the assertion fails, ```getDualSolVal``` returns 0, even with ```boundconstraint=True```. As a side not, it's annoying that sol is not capitalized in ```getDualsolLinear```` _Originally posted...
I am working on a pricer and my objective is to define the subproblem only once, in order to avoid unnecessary time with building the model every iteration. For this,...
Hello! I try to add my own heuristic, which called while branching and give primal solutions to SCIP. This heuristic works only with original problem, but after presolving SCIP add...
It might be my implementation error, but whenever I have indicator constraints, the constraints seem always needs to be satisfied regardless of the value of the binary variable. Minimum example:...
**Describe the bug** Function `cuttingstock()` is not giving the correct answer for the following example: ``` # item widths widths = [3, 2, 1] # width demand demand = [3,...
**Describe the bug** I am trying to use the count feature. I correctly get the number of solutions but when I try to get the solutions an empty array is...
**Describe the bug** After upgrading SCIPOptimization suite to 9.0.0 and pyscipopt to 5.0.0., it is not possible to use the same code in debug mode in Pycharm. Impor of pyscipopt.Model...
