Fast equality test for straight-line compressed strings
The paper describes a simple and fast randomized test for equality of grammar-compressed strings. The thorough running time analysis is done by applying a logarithmic cost measure.
متن کاملEquality Testing of Compressed Strings
This paper gives a survey on efficient algorithms for checking equality of grammar-compressed strings, i.e., strings that are represented succinctly by so called straight-line programs.
متن کاملAn Efficient Algorithm to Test Square-Freeness of Strings Compressed by Balanced Straight Line Programs
In this paper we study the problem of deciding whether a given compressed string contains a square. A string x is called a square if x = zz and z = uk implies k = 1 and u = z. A string w is said to be square-free if no substrings of w are squares. However, very little is known for testing square-freeness of a given compressed string. In this paper, we give an O(max(n2,n log2 N))-time O(n2)-spac...
