Abstract
We present two new techniques for trimming a logarithmic factor from the running time of efficient parallel algorithms for graph problems. The main application of our techniques is an improvement in running time from O (log2 n) to O(logn) for efficient triconnectivity testing in parallel. Additional applications include almost optimal O(logn) time algorithms for recognizing Gauss codes, for testing planarity of graphs with a known Hamiltonian cycle and for testing if a permutation is sortable on two stacks.
