不过,在此之前,请大家确保自己的branch and bound和column generation的知识务必过关,而且是非常熟悉的那种。 因为branch and price算法就是branch and bound和column generation的结合体。 2 应用背景 branch and price算法就是branch and bound和column generation的结合体。具体是怎么结合的呢?先看一张BP的算法流程图...

Hence, advanced algorithms are needed to solve the 2E-IRP heuristically and optimally. This paper proposes a novel exact branch-and-price algorithm for the 2E-IRP. The contributions are threefold: • We propose a mathematical model for the 2E-IRP, where customers can be visited from any ...
