It would be helpful if you could add some details, such as - a plain text version of the model, - the output from running the optimization, - what the...
I could read the text file, I was just hoping you could create both a human-readable version of the model (like you would write in a paper) and the input...
Sorry for not responding to this at the time. If you would still like an answer, please post more details, such as how you downloaded and built MibS, what compiler,...
Thanks for reporting this and sorry that I haven't gotten to look at it yet. The sensitivity analysis features of SYMPHONY have not received a lot of exercise. @bsuresh Might...
@SelinBayramoglu I probably should have given you this answer right off the bat, but had to refresh my memory. The `WS` ("warm starting") branch has a lot of fixes for...
This is an internal code that should not be returned to the user. Just eyeballing the code now, I don't see any execution path that would allow it. Can you...
One thing I can see by inspection is that your `start` array is wrong. It should have length `n_cols+1` `start[n_cols+1]` should be equal to `non_zeros`. In your case, it would...
Oops, sorry, I made a mistake in my response above that has now been corrected. The format used here is what is called Compressed Sparse Column format. It is explained...
