A Simple Alphabet-independent Fm-index
Abstract. We design a succinct full-text index based on the idea of Huffmancompressing the text and then applying the Burrows-Wheeler transform over it. The resulting structure can...

Making AC-3 an Optimal Algorithm
The AC-3 algorithm is a basic and widely used arc consistency enforcing algorithm in Constraint Satisfaction Problems (CSP). Its strength lies in that it is simple, empirically ef...

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...
