Abstract
We consider the problem of designing an efficient index for approximate pattern matching. Despite ongoing efforts, this topic is still a challenge in combinatorial pattern matching. We present a new data structure that allows to report all matches in worst-case time O(|Σ|m+occ), which is linear in the pattern length m and the number of occurrences occ for alphabets of constant size |Σ|. Our index uses O(n|Σ|logn) extra space on average and with high probability, where n is the length of the text (indexing) or the number of strings to index (dictionary lookup).
