Attached are the LP and MPS files for a MILP problem which has a provably optimal objective function of > -14.0 but HiGHS declares it as provably optimal at -18.2.
Even when the HiGHS relative and …

A natural addition is a function to find isomorphisms between graphs. I've written some code that does that. (I'm sure it works for simple graphs and simple digraphs. Not sure about weighted.) I hope …

I'm using `HiGHS version 1.7.2 Githash 5ce7a2753. Copyright (c) 2024 HiGHS under MIT licence terms` on commandline on Windows 11.
Very frequently, calling highs with an lp-file hangs the program, e…

**Describe the bug**
Import teaserpp_python before scipy may cause scipy to use the system path to libstdc++.so instead of the one in anaconda.
Error message looks like this:
```
Traceback (most r…

Sometimes it is possible for one to only care for junior high or senior high. Since few people in junior high schools participate in NOI or CTSC, it is suggested to separate junior high from senior hi…

For integer linear program models created via `highspy` v1.7.1, it seems that models created with `addCol` run a bit faster than models created with `addVariable`. The timing data below show this occu…

### Describe your issue.
The below code gives infeasibility, however one solution would be x1=0, x2=0.
Note that using `h=10**11` or `h=10**13` gives feasibility.
### Reproducing Code Example…

I have a primal infeasible model where I want to find the dual objective value (following the Benders' tutorial on generating feasibility cuts). While solving the problem in HiGHS (v1.9.3) takes less …
