Superstrings have many applications in data compression and genetics. However the decision version of the shortest superstring problem is NP-complete. In this paper we examine the complexity of approximating a shortest superstring. There are two basic measures of the approximations: the compression ratio and the approximation ratio. The well known and practical approximation algorithm is the se...
