SpletWe study the vertex decremental Single-Source Shortest Paths (SSSP) problem: given an undirected graph G = (V,E) with lengths ℓ(e) ≥1 on its edges that undergoes vertex deletions, and a source vertex s, we need to support (approximate) shortest-path queries in G: given a vertexv, return a path connectings tov, whose length is SpletA shortest path from u to v is any path such that w ( p) = δ ( u, v ). Note that every vertex has a path of length 0 to itself. Therefore, when all weights are positive, δ (v, v) = 0 (not ∞), …
