Retrieving simplex iterations information through callbacks

[fontanf]

Hi,

Is there a way to retrieve simplex iteration / objective / infeasibilities through callbacks?

With the kCallbackLogging, I managed to get the solver output. I could parse it, but that's a bit tedious.

I couldn't find how to get this information from the HighsCallbackOutput structure.

If you want this during the solve phase, it's not possible at present. After the solve is complete, use the data in HighsInfo

I meant during the solve phase. Thank you for the quick answer.
