Abstract
The k-anticover of a string S is a set of distinct k-length substrings such that every index in S is contained in one of these substrings. The existence of an anticover indicates a lack of structure in S. It was recently proven by Alzamel et al. [2] that finding whether or not a k-anticover exists is-Hard for. In this paper, we extend the definition to provide three optimization versions for the k-anticover problem. We provide efficient approximation algorithms for these problems.
