WebOct 29, 2015 · For a path P ⊂ G, the bottleneck length b l ( P) is the maximum edge weight on P. The bottleneck distance b i j is the minimum bottleneck length, ie. b i j = m i n { b l ( P) P is an i − j path } it then goes on to say that " b i j is equal to b l ( T { i j }) where T denotes the MST on G ".
