WebMar 1, 2014 · We extend the Burrows-Wheeler transform (BWT) of strings to acyclic directed labeled graphs, to support path queries as an extension to substring searching. We develop, apply, and tailor this technique to a) read alignment on an extended BWT index of a graph representing pan-genome, i.e., reference genome and known variants of it; and … WebMar 1, 2024 · This algorithm relies on graph isomorphism being computable in strictly sub-exponential time; We define an optimization variant of the problem called Wheeler Graph Violation, abbreviated WGV, where the aim is to identify the smallest set of edges that have to be removed from a graph to obtain a Wheeler graph.
