%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% *OPTE Special Issue: TriPod-MOPTA 2018 on Energy and Optimization* *Submission Due Date:* October 30, 2018 *Guest Editors:* Daniel Bienstock, Professor, Industrial Engineering and Operations Research/Applied Physics and Applied Mathematics, Columbia University. ⟨ dano@ieor.columbia.edu⟩. Luis F. Zuluaga, Associate Professor, Industrial and Systems Engineering, Lehigh University. ⟨luis.zuluaga@lehigh.edu⟩. *Aim:* This call aims at publishing research work that showcases the interactions between Optimization and Engineering to address important problems arising in the Energy sector. The call encourages submissions from speakers at the upcoming TriPod-MOPTA 2018, *but is open to submissions from any interested authors*. The call is *open to all types of papers, including theoretical, applied, and algorithmic articles, as well as articles that combine these features.* *Theme:* The rapid and imperative changes in the Energy sector have created a wide range of challenges that are being addressed by a combination of Engineering and Optimization techniques. For example, consider the use of convex relaxations to obtain near-optimal alternating current optimal power flow (ACOPF) solutions, or for gas distribution network problems; the use of multi-level optimization to address commodity pricing problems, integration of renewable energy sources (RES) into electricity markets, or to immunize a commodity network against potential attacks; the use of uncertainty optimization techniques to address challenges related to the use of RES, immunize commodity networks against catastrophic events, and obtain robust equilibrium commodity prices that take into account uncertainty in commodity production or demand; the development of improved mathematical formulations and optimization solution methods, to address large-scale Energy related problems; among many other interesting research directions that are being explored towards the goal of designing commodity networks that are “smart”, interconnected, efficient, reliable, resilient, and environmentally responsible. Beyond the study of individual commodity networks, nowadays, very interesting research addresses the challenging problem of studying the interaction between different commodity networks such as electricity, gas, and water networks, as well as the interaction of these networks with communication and transportation networks. *Submission Procedure:* Please submit to the *Optimization and Engineering (OPTE)* journal at https://www.springer.com/mathematics/journal/11081 and select special issue “SI: TriPod-MOPTA 2018”. All sub- missions must be original and may not be under review by another publication.
