I have searched everywhere for information about how big problems the glpsol tool version 4.8 can manage. I found that version 4.3 could manage 100.000 constraints and 1000 variables. I don't think this is true for version 4.8. In an university project I developed an problem with 1680 variables, and it could be solved within reasonable time. Where can I find any information about this topic? Any help is appreciated.
Thank you very much for a wonderful tool and any help being posted in this forum! Keep up the good work.

It worked, an reply to my question was posted shortly after I sent my mail to help-glpk@gnu.org
The answer is. There is no limit except the amount of memory available. It's a larger problem with integer variables, because then it will depend on the structure of the instance.
Try it out... and you will find out... but no official limit!
