We present an efficient parallel algorithm for the tree-decomposition problem Ε½ 3 . Ε½. for fixed width w. The algorithm runs in time O O log n and uses O O n processors on an ARBITRARY CRCW PRAM. The sequential complexity of our tree-decom-Ε½ 2 . position algorithm is O O n log n . The tree-decomposi
For a subset S of a group G such that 1 / β S and S = S -1 , the associated Cayley graph Cay(G, S) is the graph with vertex set G such that {x, y} is an edge if and only if yx -1 β S. Each Ο β Aut(G) induces an isomorphism from Cay(G, S) to the Cayley graph Cay(G, S Ο ). For a positive integer m, th
