Abstract

The k-ary n-cube has been one of the most popular interconnection networks for distributed-memory parallel systems. In this paper, we study the problem of embedding cycles of various lengths into faulty k-ary n-cubes. It is proved that a faulty k-ary n-cube with f"v faulty vertices and f"e faulty edges admits a fault-free cycle of every even length from 4 to k^n-2f"v if k=4 is even and f"v+f"e==4 is even and f"v+f"e=
