WebThis is an all-pairs shortest path algorithm that can handle negative weighted edges. Running Time: 𝑂(𝑛 3 ) SCC’s Input: 𝐺(𝑉, 𝐸) 𝑖𝑛 ... Use When: Y ou have an unweighted SSSP(Single Source Shortest Path) WebFor each vertex v, let leveli(v)denote the unweighted shortest path distance from s to v in Gi, or equivalently, the level of v in a breadth-first search tree of Gi rooted at s. Our first observation is that these levels can only increase over time. Lemma 1. leveli+1(v) leveli(v)for all vertices v and integers i.
