Mantaining Dynamic Matrices for Fully Dynamic Transitive Closure

  title={Mantaining Dynamic Matrices for Fully Dynamic Transitive Closure},
  author={Camil Demetrescu and Giuseppe F. Italiano},
In this paper we introduce a general framework for casting fully dynamic transitive closure into the problem of reevaluating polynomials over matrices. With this technique, we improve the best known bounds for fully dynamic transitive closure. In particular, we devise a deterministic algorithm for general directed graphs that achieves O(n 2) amortized time for updates, while preserving unit worst-case cost for queries. In case of deletions only, our algorithm performs updates faster in O(n… CONTINUE READING
