The Fault-Tolerant Extension Problem for Complete Multipartite Networks
February 1994 (vol. 5 no. 2)
pp. 205-210

We develop a characterization for m-fault-tolerant extensions, and for optimalm-fault-tolerant extensions, of a complete multipartite graph. Our formulation shows thatthis problem is equivalent to an interesting combinatorial problem on the partitioning ofintegers. This characterization leads to a new procedure for constructing an optimalm-fault-tolerant extension of any complete multipartite graph, for any m/spl ges/0. Theproposed procedure is mainly useful when the size of the graph is relatively small,because the search time required is exponential. This exponential search, however, is notalways necessary. We prove several necessary conditions that help us, in several cases,to identify some optimal m-fault-tolerant extensions without performing any search.
