Abstract

The k-mappability problem is defined as follows: Given a sequence S[1, n] of length n over a constant alphabet Σ, and two integers k andm ≤ n, compute an array Fk , such that: Fk [i] = |{j , i | dH (S[i, i +m - 1], S[j, j +m - 1]) ≤ k}| The function dH (,) denotes the hamming distance. Derrien et al. [2] introduced this problem in the context of genome analysis. We propose a provably efficient algorithm for 1-mappability with O(n logn) worst case run time. The previous best known bound is O(n log2 n) [1].
