Can I write Gurobi log file in csv form?
Answered
I am wondering if I can have my Gurobi log file in different formats other than txt file.
For instance, is there a Gurobi feature/module/code/whatever that I can change the branch-and-cut tree search section of the log (example shown below) into csv. I am using Python. Should I play around with the text file (read and extract data?). If so, is there a clever way to do it?
