Webspecial case, Chan showed that shortest paths in real vertex-weighted graphs can be solved in O(n2.844) time. Very recently Shapira et al. [17] and Vassilevska et al. [23] considered the all pairs bottleneck paths problem (APBSP, also known as the maximum capac-ity paths problem) in graphs with real capacities as-signed to edges/vertices. 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.

It’s a fairly easy to show that the maximum-bottleneck (s,t)-path in a directed graph can be computed in O(ElogV)time using a variant of Jarník’s minimum-spanning-tree algorithm, or of Dijkstra’s shortest path algorithm. Simply grow a directed spanning tree T, rooted at s.
