Les 21ièmes Journées Graphes et Algorithmes (JGA 2019) auront lieu à Bruxelles, du 13 au 15 novembre 2019. Il s'agit du rendez-vous annuel de la communauté francophone de la théorie des graphes et de ses applications.
The many-visits traveling salesperson problem (MV-TSP) asks for an optimal tour of n cities that visits each city c a prescribed number kcof times. Travel costs may not be symmetric, and visiting a city twice in a row may incur a non-zero cost. The MV-TSP problem finds applications in scheduling, geometric approximation, and Hamiltonicity of certain graph families. The fastest known algorithm for MV-TSP is due to Cosmadakis and Papadimitriou (SICOMP, 1984).
Today Tony will tell us about Transfinite Ford-Fulkerson on a Finite Network.
