WebGraph Traversal The most basic graph algorithm that visits nodes of a graph in certain order Used as a subroutine in many other algorithms We will cover two algorithms – … WebJohnson's Algorithm solves this problem more efficiently for sparse graphs, and it uses the following steps: Compute a potential p for the graph G. Create a new weighting w ′ of the graph, where w ′ ( u → v) = w ( u → v) + p ( u) − p ( v). Compute all-pairs shortest paths d i s t ′ with the new weighting.
