摘要

大多数需要图论的实际问题都涉及到大图——这些图实际上是不可能手工计算的。事实上,最近人们对图论的兴趣增长的原因之一是高速电子计算机的到来。本文提出了一种利用并行架构机器的计算能力优势的算法——共享内存分割总线系统。该算法是利用该系统对给定图进行邻接矩阵的乘法运算。因此,它根据图中是否存在奇环来判断图是否是二部图。该算法的仿真模型显示了良好的效果。

An algorithm for a special graph
Most of practical problems which call for graph theory involve large graphs - graphs that are virtually impossible for hand computation. In fact, one of the reasons for the recent growth of interest in graph theory has been the arrival of the high-speed electronic computer. In this paper, we propose an algorithm which take the advantages of computing power gained from a machine with parallel architecture - A shared memory split bus system. The algorithm is to perform multiplications of adjacency matrices for a given graph using such system. Therefore, it determines whether the graph is a bipartite or not based on the existence of odd cycles in the graph. The simulation model for such an algorithm has shown some favorable results.
