[SCIP] How can I recognize the type of pricing variable in a branch-and-price process?

[杨瑞光]

Hi, 


everyone,


I'm working on a variant problem of VRP based on the VRP example coded in C++ given on the SCIP website. I try to implement a branch-and-price algorithm for my problem. But, in my problem, I need to solve two different pricing subproblems for the same RMP (Restricted Master Problem). And these two pricing subproblems will produce two different types of pricing variables for the RMP. And I don't know how to identify which type of variables the algorithm adds to the RMP. May I ask how I can handle this problem?


Thanks a lot!


Best wishes
