A suffixient set is a novel combinatorial object that captures the essential information of repetitive strings in a way that, provided with a random access mechanism, supports various forms of pattern matching.

摘要

A suffixient set is a novel combinatorial object that captures the essential information of repetitive strings in a way that, provided with a random access mechanism, supports various forms of pattern matching. In this paper, we study the size \(\chi \) of the smallest suffixient set as a repetitiveness measure: we place it between known measures and study its sensitivity to various string operations.
