3rd Workshop on Combinatorial Optimization

Zoom Platform |

The third edition of the Workshop on Combinatorial Optimization will occur in an online format on June 24th 2022 and is organized by CMAFcIO (The Center for Mathematics, Fundamental Applications and Operations Research the Faculty of Sciences of the University of Lisbon) and CEGIST’s research area MOSAIC. 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.
