Shortest Paths and Transitive Closure

1992
Let G = (V, E) be an undirected graph and let l be a function assigning a nonnegative length to each edge. Extend l to domain V x V by defining l(υ, υ) = 0 and l(u, υ) = ∞ if (u, υ) ∉ E. Define the length2 of a path \( p = {e_{1}}{e_{2}}...{e_{n}}{\text{ to be }}l(p) = \Sigma _{{i = 1}}^{n}l({e_{i}}). \).
