Nonoverlapping SPM, as a branch of gap constraint SPM, means that any two events cannot use the same sequence page in the same place because the occurrences. Nonoverlapping SPM makes a balance between performance and completeness. The frequent patterns discovered by present techniques usually contain redundant patterns. To reduce redundant patterns and improve mining overall performance, this paper adopts the closed structure mining method and proposes a total algorithm, called Ne
