Abstract:The largest area first parsing of a string often leads to the best results in grammar compression for a variety of input data. However, the fastest existing algorithm has Θ(N 2 log N ) time complexity, which makes it impractical for real-life applications. We present a new largest area first parsing method that has O(N 3 ) complexity in the improbable worst case but works in the quasilinear time for most practical purposes. This result is based on the fact that in the real data, the sum of all depths of an LCP… Show more
