Abstract

In this paper, we study the linear layout problem of an incomplete hypercube by the embedding-in-book technique. An incomplete hypercube is a generalization of the hypercube in the sense that the number of nodes can be an arbitrary number. Embedding a graph in a book is to place nodes on the spine of a book and to draw the edges such that edges residing in a page do not cross. In this paper, we propose a scheme to embed an incomplete hypercube of 2^n+2^m nodes, where nm=0, with n-1 pages, cumulative page width 2^n+2^m-3; and book width 2^n^-^1+2^m^-^1 for nm0, 2^n^-^1 for nm=0. Moreover, this scheme can be applied to an arbitrary size of an incomplete hypercube.
