Abstract
A set of subgraphs C(1), C(2),...,C(k) in a graph G is said to identify the vertices (resp. the edges) if the sets {j: v is an element of C(j)} (resp. {j: e is an element of C(j)}) are nonempty for all the vertices v (edges e) and no two are the same set. We consider the problem of minimizing k when the subgraphs C(i) are required to be cycles or closed walks. The motivation comes from maintaining multiprocessor systems, and we study the cases when G is the binary hypercube, or the two-dimensional p-ary space endowed with the Lee metric.
