It is a combinatorial problem with great significance in practics to obtain the bandwidth of a graph. However, it has been shown that algorithmic determination of the bandwidth of a graph is an NP-complete problem even for a tree. So it is attractive to get thc bandwidths of some special, classes, of graphs.In 1976, Dewdney announced in a survery, that the bandwidth of the discrete tori Cm × Cn is an unsolved problem. In this paper, we has solved this problem, i.e., we obtain the following...

It is a combinatorial problem with great significance in practics to obtain the bandwidth of a graph. However, it has been shown that algorithmic determination of the bandwidth of a graph is an NP-complete problem even for a tree. So it is attractive to get thc bandwidths of some special, classes, of graphs.In 1976, Dewdney announced in a survery, that the bandwidth of the discrete tori Cm × Cn is an unsolved problem. In this paper, we has solved this problem, i.e., we obtain the following results:Theorem 1. If m≠n and min(m, n)≥3, then the bandwidth of the discrete tori Cm×Cn is 2 min(m, n);Theorem 2. If n≥3, then the bandwidth of the discrete tori Cn×Cn is 2n-1,

求一个图(Graph)——或一个对称矩陣——的带宽(Band width)是一个很有实际意义的組合問題。已經証明,即使对于树形图(Tree)来說,确定它的带宽問題也属于NP—完全类。因此,求出一些特殊类型的图的带宽就更加引人注目。事实上,能够定出其带宽的图很少。除了一些很簡单的情形外,迄今已知的主要結果只有完全偶图K_(m:n)、n維方体Q_n、平面格子图P_m×P_n和柱面上的格子图C_m×P_n。Dewdney在1976年所作的关于图的带宽的一篇綜述报告中,提出了三个沒有解决的問题。其中一个是求环面上格子图C_m×C_n的带宽。本文解决了这个問題,我們得到下述結果: 定理1.当m≠n且min(m,n)≥3时,环面上格子图C_m×C_n的带宽为2min(m,n); 定理2.当n≥3时,环面上格子图C_n×C_n的带宽为2n—1.

A complementary partitive graph is a bipartite graph G(V', V"; E) with disjoint vertex sets V', V", and an edge set E such that all edges are directed except only one edge, say j=[x, y], is undireeted, and the outgoing degrees are d+(x)=0, d+(y)=0 and d+(v)=1 for all v≠x, y. The following assertions can be easily proved: If G(v', V"; E) is a complementary partitive graph with undireeted edge j, then a pair of eomple mentary partitions P'(E) and P"(E) with respect to j can be constructed by...

A complementary partitive graph is a bipartite graph G(V', V"; E) with disjoint vertex sets V', V", and an edge set E such that all edges are directed except only one edge, say j=[x, y], is undireeted, and the outgoing degrees are d+(x)=0, d+(y)=0 and d+(v)=1 for all v≠x, y. The following assertions can be easily proved: If G(v', V"; E) is a complementary partitive graph with undireeted edge j, then a pair of eomple mentary partitions P'(E) and P"(E) with respect to j can be constructed by the edges incident with each vertex of V' and eaeh vertex of V". Conversely, if Hk has a com-plementary partition with respect to j, then a complementary partitive graph can be constructed.By using the complementary partitive graph defined above. We can ease the proofs of theorems of complementary partitions established by W. K. Chen (1969, 1976) and give a simple criterion to determine whether or not a complementary partition is essen-tial as follows:Theorem A complementary partition is essential if and only if the corresponding com-plementary partitive graph is a connected graph.
