Arc-Flags in Dynamic Graphs

Emanuele Berrettini, Gianlorenzo D'Angelo & Daniel Delling
Computation of quickest paths has undergoing a rapid development in recent years. It turns out that many high-performance route planning algorithms are made up of several basic ingredients. However, not all of those ingredients have been analyzed in a \emph{dynamic} scenario where edge weights change after preprocessing. In this work, we present how one of those ingredients, i.e., Arc-Flags can be applied in dynamic scenarios
