Workshop on Combinatorial Optimization

Zoom Platform |

The Workshop on Combinatorial Optimization will take place on December 10th, 2021. This Workshop is organized by CEGIST’s research area MOSAIC, in a joint collaboration with CMAFcIO (The Center for Mathematics, Fundamental Applications and Operations Research the Faculty of Sciences of the University of Lisbon), and will occur in an online format - zoom link available soon. This Workshop will gather specialists in the field of Combinatorial Optimization, from several countries, to present and discuss recent research work around this subject.

Professor José Rui Figueira, President of CEGIST, will present the Opening Session, alongside Professor Luís Gouveia, Coordinator of CMAFcIO. CEGIST member Daniel Santos will present the final session, with the theme “Compact formulations for multi-depot routing problems”.
