摘要:
We present a parallel algorithm for a novel problem in a graph's open ear decomposition. The algorithm runs in O(log n) time with n processors on a CREW PRAM, where n is the number of vertices and m is the number of edges in the graph. We apply this result in parallel algorithms to solve the two vertex disjoint s-t paths problem in O(log n) time with n + m processors and the maximal path problem in planar graphs in O(log2 n) time with O(n) processors. Both of these algorithms run on the CRCW PRAM.
