[SCIP] Access Dual Values with SCIP

[Enrico Calandrini]

Hi everyone,
I hope this message finds you well.

I am currently working with SCIP and have a question regarding the retrieval of dual values. Specifically, I would like to confirm whether it is necessary to disable presolve in order to access dual values reliably.

Could you kindly clarify how presolve interacts with dual value computation and if there are any recommended settings to ensure the dual values can be retrieved without issue?

Thank you very much for your time and assistance. I appreciate the incredible work you’ve done with SCIP!

Looking forward to your response.

Best regards,
