5th Workshop on Combinatorial Optimization

The 5th Workshop on Combinatorial Optimization will take place online on June 6th, 2023. This Workshop is co-organized by three research centers of the University of Lisboa (ULisboa), namely, CMAFcIO (Center for Mathematics, Fundamental Applications and Operations Research, Faculty of Sciences), the MOSAIC group of CEGIST (Centro de Estudos de Gestão, IST – Técnico Lisboa), and CEMAPRE (Centro de Matemática Aplicada à Previsão e Decisão Económica, ISEG – Lisbon School of Economics and Management), and will occur in an online format – via Zoom (https://videoconf-colibri.zoom.us/j/85678705707). Following the previous editions, this 5th edition will once again gather specialists in the field of Combinatorial Optimization, from several countries, to present and discuss recent research work.
