A nonlinear integer programming (NLIP) model is first developed for the DN problem. By exploring the structure of the proposed model, an effective heuristic solution method consisting of optimization ...

This paper presents a hybrid evolutionary algorithm to solve mixed-integer nonlinear bilevel programming problems, in which integer decision variables are controlled by an upper-level decision maker ...

This study proposes a comprehensive strategy to optimize the operation of real-world gas pipeline networks and support decision-making. The goal is to improve environmental sustainability by ...
