[SCIP] Creating another SCIP instance inside a SCIP branch and price subroutine

[Xie, Yujia]

Hi,

I'm implementing a SCIP branch and price problem using C++, and I need to incorporate the early termination for pricing iterations (i.e., timeout) by returning DIDNOTRUN result as well as a lowerbound. In order to compute this lowerbound, I'm solving a LP relaxation of another problem.

I was trying to create (and breakdown) another SCIP environment within the necessary pricing iterations, but I kept running into errors after the first solve (i.e., the LP relaxation solved for the first time, then it either goes into segmentation fault or abort the second time onward).

Can anyone advise?

Sincerely,
Yujia
