Bellman-Ford in Almost-Linear Time
Isaac M. Hair, George Z. Li, Jason Li +1
We consider the single-source shortest paths problem on a directed graph with real-valued (possibly negative) edge weights and solve this problem in time.

Improved Strongly Polynomial Work-Span Tradeoffs for Directed Single Source Shortest Paths
Isaac M. Hair, George Z. Li, Jason Li +1
We revisit the single-source shortest paths (SSSP) problem on directed graphs with nonnegative real weights and give a deterministic parallel algorithm with $O(n^{1+o(1)}t^2 + m^{1…
