<div dir="ltr">Hello!<div><br></div><div>There might be a more sophisticated approach, but I believe you can achieve what you want with the variable names. E.g., the master variables whose columns come from pricing problem 1 will be called "1_XXX", and the ones from pricing problem 2, "2_XXX". Then it's just a matter of getting the name of the variables.</div><div><br></div><div>Best,</div><div>João </div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Sun, Jan 12, 2025 at 7:41 AM 杨瑞光 <<a href="mailto:yrgys@foxmail.com">yrgys@foxmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div>Hi, </div><div><br></div><div>everyone,</div><div><br></div><div>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?</div><div><br></div><div>Thanks a lot!</div><div><br></div><div>Best wishes</div>_______________________________________________<br>
