The method includes inputting a plurality of strings into a compression engine. The method also includes converting each of the plurality of strings into a new, prefix-preserving compressed string, using the compression engine. For every string P that is a strict prefix of a string S, P's ...
Space-time Trade-offs for the LCP Array of Wheeler DFAs Recently, Conte et al. generalized the longest-common prefix (LCP) array from strings to Wheeler DFAs, and they showed that it can be used to efficiently determine matching statistics on a Wheeler DFA [DCC 2023]. However, storing th...
