[SCIP] PYSCIPOPT Model Methods writeLP and trySol

[Graczyk, Christoph]

Hi,

If you are working with PyScipOpt I would suggest you visit the repository at https://github.com/scipopt/PySCIPOpt for specific support and make an issue (including your code) so we can better understand the problem and help you fix it. You can also search through existing issues for branch and price (e.g. https://github.com/scipopt/PySCIPOpt/issues?q=branch+and+price), or the exact function that is not working for you and possibly find a solution in some issue of the past.

Without your code example it is difficult to give you specific support.


Best regards,

Christoph

Betreff: [SCIP] PYSCIPOPT Model Methods writeLP and trySol

Dear Team,

I am currently working with the Pyscipopt interface to set up a Branch and Price Solver using the language Python. However, I came to realize that trySol and writeLP are not working for me. I tried these commands on Visual Studio Code and Anaconda Spyder. Simply nothing seems to happen after adding the solution. In Spyder the Input number jumps back to „In [1]“ and saved objects seem to be inaccessable.

Do you know About this issue? If so, I would be glad to know how to fix this issue. I was trying to use the trySol command to add a starting solution to my model. So I am looking forward to at least get this method working.

Thanks for your time.

Kind regards
Jan Fischer
