Our team successfully used PySCIPOpt 4.2.0 with **SCIP 8.0.0** (Linux Ubuntu 20.04, Python 3.8.10). But when we had built **SCIP 8.0.1** and then recompiled PySCIPOpt for this new version all...
Based on pull request in #418 Changelog updated. Should the parameter "stickingatnode" in the addConsLocal function be True or False? There are now two separate createCons functons, old: def createCons(self,...
I'm trying test example: ``` from pyscipopt import Model model = Model("Example") # model name is optional x = model.addVar("x") y = model.addVar("y", vtype="INTEGER") model.setObjective(x + y) model.addCons(2*x - y*y...
How to set primal starting value？There is a method(Start) in gurobi to set the initial solution. Thanks
Hi guys, I had a quick question on implementing branch and price using pySCIPOpt. The issue https://github.com/scipopt/PySCIPOpt/issues/395 was very helpful in explaining how to implement branch and price in pySCIPOpt....
I am trying to implement a Branch-and-Price algorithm. Pricing new variables already works fine but I have some issues when it comes to branching. I already came up with a...
This code ([test.zip, adapted from atsp.py](https://github.com/scipopt/PySCIPOpt/files/8787127/test.zip))  yields this output  I do not know if this is desired behavior, but I find it to be counterintuitive. A copied model...
Using a simple example, diet.py when I introduce model.freeTransform() in line 98, the debugging in vscode starts to behave in unexpected ways. Placing a breakpoint between lines 97 and 102...
Hi all, I just noticed that during solving, calling ```getCutLPSolCutoffDistance(cut, model.getBestSol())``` causes the solving to exit silently (i.e., terminate without any warning or error), if no incumbent exists (```model.getNSols() =...
I wanted to understand how to implement a constraint handler and had some questions regarding that - - In this example [lotsizing_lazy.py](https://github.com/scipopt/PySCIPOpt/blob/master/examples/finished/lotsizing_lazy.py), do we expect the objective function values of...
