Hi Jaromil, I couldn't try the MPS version yet, sorry.  The problem occurs for some inputs and for some not. But it is always the same inputs where it occurs. So yes it is reproducible. I have the ...

Thanks Jaromil, I am always tracking my memory simultaneously. It is at around 85-95% most of the time until it hits the root simplex log where I have the feeling of getting stuck. Then it slowly d...

I ran out of memory when trying the DegenMove == 0. Maybe in the end this is the problem but I do not understand why... and also why I do not get a memory error. Before I had two quadratic constrai...

Another thing that is quite weird: This is another example but why does it do iteration 965072 twice? It should be done after the first time as far as I understand. Same happened in the example ab...

Thanks Jaromil, Yes I can imagine that it is hardly to tell just from the log file ;) It is not the numeric issue. I resolved them (it was a huge big M number).  I will try the suggestion with the ...

I am working on this right now thanks. It is definitely not a memory issue. Do you have any idea what could cause this. I find it weird as according to the gurobi documentation the fact that Primal...

Hi Jaromil,   Thanks for the answer. Unfortunately, I cannot because it is more than 1000 lines of code and depending on input files. Also, for some certain input scenarios it works. Can it be due ...

Thanks Alison I will give that a try. I jus made it to 3493 nodes before running into an error.

Update: I changed the NodeFilestart parameter to 0.5 but I would still run into memory issues during the relaxation process. I got a bit further regarding number of nodes explored. If I go even low...

Hi Alison, thanks heaps for the help. I use Pyomo in the Python consol but I guess it would still not work. Thanks for tip regarding the memory issue. I will give it try and see what the model will...
