Repetitive strings have been studied in such diverse fields as molecular biology, data compression, etc. Some important regularities that have been studied are periods, covers, seeds and squares. A natural extension of the repetition problems is to allow errors. Among the four notions above, approximate squares and approximate periods have been studied.In this paper, we introduce the notion of approximate covers which is an approximate version of covers. Given two strings P`(|P`|=m)
