GOM Seminar: Eglantine Camby, Monday, March 26th 2018 – A parallel algorithm using VNS and VND with shared memory and message passing interface

Date: March, 26th, 11h00 Place: Université Libre de Bruxelles Abstract: In this talk, we present diverse concepts: Variable Neighborhood Search, Variable Neighborhood Descent, parallel algorithm, shared memory, message passing interface and community detection. Besides, we explain how can we use all of them in only one algorithm. Some numerical results…

GOM Seminar: Alejandro Jofre, Monday, January 29th 2018 – Optimization and game theory in Energy markets

Date: January, 29th, 11h00 Place: ULB Bruxelles Abstract: In this talk we introduce an stochastic optimization/game-theory model to describe an energy market working on a network (transmission), including renewal energy suppliers, distributed generators and demand nodes. We characterize Nash equilibria and pricing rules in this stochastic setting as well as…

INOCS Seminar: Victor Bucarey Lopez, Friday, December 12th 2017 – Solving strong Stackelberg equilibrium in stochastic games

Date: December, 12th, 12h00 Place: Inria Lille-Nord Europe Abstract: In this work we face the problem of finding strong Stackelberg equilibrium in stochastic games. We study a familiy of stochastic games where equilibrium in stationary policies exist and prove the convergence of value iteration and policy iteration procedures. Preliminary computational…

OPTIMA Seminar: Juan José Palacios Alonso, Wednesday, November 15th 2017 – Fuzzy numbers for scheduling problems with uncertainty

Date: November, 17th, 16h00 Place: Inria Lille-Nord Europe Abstract: In optimization problems, it is common the case where the value of some variables is not well known, or it is uncertain. Traditionally, this uncertainty has been dealt with, from the point of view of Stochastic Optimization, which models these variables…

OPTIMA Seminar: Dimitri Papadimitriou, Friday, November 17th 2017 – Location-Routing Models for Data Distribution Systems

Date: November, 17th, 11h00 Place: Inria Lille-Nord Europe Abstract: Given a set of client demands and potential facility locations, the (discrete) capacitated facility location problem (cFLP) consists in selecting a subset of locations where to install a facility, and assigning demands to these facilities without exceeding their capacity. In this…
