Python interface to SCIP persistent solver

We should explore this for a persistent solver interface to SCIP:

Hi! I am about to have a go at this, as I need to add lazy constraints to the SCIP backend. Just checking if anybody here has done some progress on this task already. Otherwise I was thinking in adapting gurobi direct/persistent solver modules. Any tips?

@michaelbynum has been developing a new framework for the persistent interfaces (see the solver-rewrite branches on his and my forks). I would suggest coordinating with him and basing your work on his.

Hi @jsiirola and @ghackebeil . Recently, I need to use SCIP in Pyomo and find this issue. Is there any progress with the SCIP interface or scip_persistent in Pyomo? Thanks.

@ZedongPeng, to my knowledge, no one is actively working on this (although I agree it would be really nice to have).

@ZedongPeng We are not actively working on a SCIP persistent interface, but we have plans to work on this over the winter.
