Near-Optimal Directed Low-Diameter Decompositions
Karl Bringmann, Nick Fischer, Bernhard Haeupler +1
Low Diameter Decompositions (LDDs) are invaluable tools in the design of combinatorial graph algorithms. While historically they have been applied mainly to undirected graphs, in t…

A Simple Parallel Algorithm with Near-Linear Work for Negative-Weight Single-Source Shortest Paths
Nick Fischer, Bernhard Haeupler, Rustam Latypov +2
We give the first parallel algorithm with optimal work for the classical problem of computing Single-Source Shortest Paths in general graphs with negative-weight edg…
