- Problem 24.3.6 (CLRS Edition 3 Page 603.
We are given a directed graph G =(V,E) on which each edge (u,v) in E has an
associated value r(u,v), which is a real number in the range 0 ≤ r(u,v) ≤ 1
that represents the reliability of a communication channel from vertex
u to vertex v. We interpet r(u,v) as the probability that the channel from u
to v will not fail and we assume that these probabilities are
independent. Give an efficient algorithm to find the most reliable path
between two given vertices.
