摘要

En 中文
The star graph interconnection network has been introduced as an attractive alternative to the hypercube network. In this paper, we consider the path embedding problem in star graphs. Assume that n >= 4. We prove that paths of all even lengths from d(x, y) to n! - 2 can be embedded between two arbitrary vertices x and y from the same partite set in the n-dimensional star graph. In addition, paths of all odd lengths from d(x, y) to n! - 1 can be embedded between two arbitrary vertices x and y from different partite sets in the n-dimensional star graph except that if x and y are adjacent, there is no path of length 3 between them. The result is optimal in the sense that paths of all possible lengths are found in star graphs. (C) 2008 Elsevier Inc. All rights reserved.
