Let G be a connected graph with n vertices. Let a be a permutation in S n . The a-generalized graph over G, denoted by P a (G), consists of two disjoint, identical copies of G along with edges £a(£). In this paper, we investigated the relation between diameter of P a (G) and diameter of G for any pe
Algorithms are presented for realizing permutations on a less restrictive hypercube model called the S-MIMD (synchronous MIMD), which allows at most one data transfer on a given communication link at a given time instant, and where data movements are not restricted to a single dimension at a given t
New deterministic algorithms for routing permutations on two-dimensional meshes are developed. On an n = n array, one algorithm runs in the optimal 2 и n y 2 steps, with maximum queue length 32. Another algorithm runs in near-Ž . optimal time, 2 и n q O O 1 steps, with a maximum queue length of only
## Abstract A polynomial time algorithm for testing isomorphism of permutation graphs (comparability graphs of 2‐dimensional partial orders) is described. It operates by performing two types of simplifying transformations on the graph; the contraction of duplicate vertices and the contraction of un
