Thanks for reporting. That is obviously not the desired behavior. We will open a ticket and take a look at it. I could reproduce it, but it would be great...

Just wanted to upload a "viable" instance file

We looked deeper into the problem and the statement that the problem is infeasible is actual correct. Nevertheless, a solution exists that is slightly infeasible. Since the violations are within...

No that is the wrong conclusion. From a mathematical standpoint the instance is infeasible. Due to the arithmetic a small tolerance is allowed and this makes in this particular edge...

We were able to locate the error and there were multiple problems: - The constraint -10000000 x = c with c smaller than the feasible tolerance. Hence the constraint was...

This should be the commit that returns the correct solution: 6b2dd64cee2d728a673ffd6b854be8f873f11a94 Would be great if you could approve this :-)

Hi James, thanks for your proposed fix and your investigation. First, to provide some context what the ParallelColumns is doing: For each column/variable, the hashes are computed and then sorted...

Hi Olivier, Thanks for reporting first of all. I am wondering which problem you want to specify. Should the variables `x1` and `x2` be free? If this is the case,...

Sorry :sob: The solution should be the following - skip substituting variable if the upper/lower-bound is implied and the (remaining) activity can be infinity - then the constraint can be...
