In recent years, significant advances have been made in the design and analysis of fully dynamic algorithms. However, these theoretical results have received very little attention …
Consider the following distance query for an n-node graph G undergoing edge insertions and deletions: given two sets of nodes I and J, return the distances between every pair of …
In the decremental (1+ ϵ)-approximate Single-Source Shortest Path (SSSP) problem, we are given a graph G=(V, E) with n=| V|, m=| E|, undergoing edge deletions, and a …
In the dynamic Single-Source Shortest Paths (SSSP) problem, we are given a graph G=(V, E) subject to edge insertions and deletions and a source vertex s∈ V, and the goal is to …

Popular fine-grained hypotheses have been successful in proving conditional lower bounds for many dynamic problems. Two of the most widely applicable hypotheses in this context …
We present the first non-trivial fully dynamic algorithm maintaining exact single-source distances in unweighted graphs. This resolves an open problem stated by Sankowski …

In this paper, we develop deterministic fully dynamic algorithms for computing approximate distances in a graph with worst-case update time guarantees. In particular, we obtain …
We study the approximability of two related problems on graphs with n nodes and m edges: n-Pairs Shortest Paths (n-PSP), where the goal is to find a shortest path between O (n) …

Among the most fundamental graph parameters is the Diameter, the largest distance between any pair of vertices in a graph. Computing the Diameter of a graph with m edges …
