Approximate String Matching over Ziv-Lempel Compressed Text
Abstract. We present a solution to the problem of performing approximate pattern matching on compressed text. The format we choose is the Ziv-Lempel family, speci cally the LZ78 an...

Boyer-Moore String Matching over Ziv-Lempel Compressed Text
We present a Boyer-Moore approach to string matching over LZ78 and LZW compressed text. The key idea is that, despite that we cannot exactly choose which text characters to inspect...

Approximate Regular Expression Searching with Arbitrary Integer Weights
Abstract. We present a bit-parallel technique to search a text of length n for a regular expression of m symbols permitting k differences in worst case time O(mn/ logk s), where s...
