A linear-time algorithm to compute the reliability of planar cube-free networks

A planar graph G=(V,E) is a cube-free graph (CF graph) if it has no subgraph homomorphic to the cube. The cube is the graph whose vertices and edges are the vertices and edges of the three dimensional geometric cube. The all-terminal reliability of a graph G whose edges can fail (with known probabilities) is the probability that G is connected. The problem of computing the all-terminal reliability of a general graph is NP-hard. An O(| V|) time algorithm for computing the all-terminal reliability of CF graphs is presented
