Computing suffix-prefix overlaps for a large collection of strings is a fundamental building block for the analysis of genomic nextgeneration sequencing data. The approximate suffix-prefix overlap problem is to find all pairs of strings from a given set such that a prefix of one string is similar to a suffix of the other. Välimäki et al. (Information and Computation, 2012) gave a solution to this problem based on suffix filters. In this work, we propose two improvements to the method of Välimäki et al. that reduce the running time of the computation.
