On an infeasible problem, with max debug level, the solver prints
"PROBLEM HAS NO INTEGER FEASIBLE SOLUTION"
but the API just proceeds without raising any exception and returns a "solution" which is…

**Describe the bug**
When we solve a MIP with a time limit and GLPK_MI, we get the following error message when the time limit is reached:
Error in if (solution[[STATUS]] %in% SOLUTION_PRESENT) { :…

GLPKBackend sets its parameter `simplex_or_intopt` to `glp_intopt_only`, whether integer variables are present or not.
Apparently this is not a great default for pure LP solving.

I am using PyPSA 0.26 and Linopy 0.2.6 on Windows.
I have a unit commitment problem that takes some time and I have decided to stop the simulation setting a MIP gap (~3%, but the number is not impor…

There is seemingly a bug with the restrict_positions_for_opposing_team method when using GLPK as a solver.
The following code works fine with the default CBC solver.

Hi Gapseq Team,
During the reconstruction of some larger strain databases we noticed that the medium gapfilling will usually fail for a few assemblies. In general, we observe the following 2 behavi…
