This book paves the way for researchers working on the sustainable interdependent networks spread over the fields of computer science, electrical engineering, and smart infrastructures. It provides the readers with a comprehensive insight to understand an in-depth big picture of smart cities as a thorough example of interdependent large-scale networks in both theory and application aspects. The contributors specify the importance and position of the interdependent networks in the context of developing the sustainable smart cities and provide a comprehensive investigation of recently developed optimization methods for large-scale networks. In the second volume of Sustainable Interdependent Networks book, the authors focus on the interdependencies of optimal operation of power and transportation networks; they discuss the optimization methods to deal with the computational complexity of them, and their role in future smart cities.
