Fault-tolerant routing is a key issue in computer/ communication networks. We say a network (graph) can tolerate l faulty nodes for a routing problem if after removing at most l arbitrary faulty nodes from the graph the routing paths exist for the routing problem. However, the bound l is usually a w

We study node-to-set and set-to-set fault tolerant routing problems in n-dimensional hypercubes r n . Node-to-set routing problem is that given a node s and a set of nodes path connects a node of and a node of . From Menger's theorem, it is known that these two problems in r n can tolerate at most
A graph G \* is a k-node fault-tolerant supergraph of a graph G , denoted k-NFT( G), if every graph obtained by removing k nodes from G\* contains G. A k-NFT(G) graph G\* is said to be optimal if it contains n + k nodes, where n is the number of nodes of G and G \* has the minimum number of edges am
GivenanodesandasetZ'={t~,..., tk} of k nodes in a k-connected graph, the node-to-set disjoint paths problem is to find k node-disjoint paths pi : s -+ ti, 1 < i < k. In this paper, we give two O(n\*) time algorithms for the node-to-set disjoint paths problem in n-dimensional star graphs G, which are
