Abstract

We present an index that stores a text of length n such that given a pattern of length m, all the substrings of the text that are within Hamming distance (or edit distance) at most k from the pattern are reported in O(m+loglogn+#matches) time (for constant k). The space complexity of the index is O(n1+ε) for any constant ε>0.
