Topic

Network optimization problems play a central role in a multitude of applications. They occur as individual optimization problems, for example, in supply chain management, project management, network design, information modeling, energy planning systems, big data processing, and many other problems in engineering and management. They are also fundamental subproblems of a multitude of complex
optimization problems including, among others, traffic planning, telecommunication network design, cable-trench problems, social networks, and many design optimization problems.
