Graph theory shortest path problems
WebJan 26, 2012 · The path with this property is called the maximin path or bottleneck path, and can be found with a straightforward set of modifications to mot shortest-path algorithms. The minimax path represents the opposite idea - the path between two points that minimizes the maximum edge capacity. Hope this helps! Share. Follow. WebWhile often it is possible to find a shortest path on a small graph by guess-and-check, our goal in this chapter is to develop methods to solve complex problems in a systematic …
