Software (open source) and Combinatorial Data

  • EIST (C++, part of next OGDF, with Manuel Fiedler):
    Computes exhaustively all edge-independent spanning trees of a graph, which gives a guarantee for the resilience of a network.

  • Combinatorial Data (standalone):
    Connectivity related graph counts, some linked with Sloane's integer sequence database.
  • MAOam (C++, part of OGDF, with Sebastian Semper and Sascha Alder):
    Extracts all maximal adjacency orderings of a graph exhaustively and visualizes the output.

  • IntervalStabbing (C++, stand-alone):
    Solves interval stabbing problems in small integer ranges faster and more directly than the state of the art before due to Chazelle (see here for more information).

  • Boyer-Myrvold (C++, part of OGDF):
    Fast O(n)-time implementation of the Boyer-Myrvold planarity test. Features additionally the extraction of multiple Kuratowski subgraphs in output-linear time, see also here.


Teaching

  • Research Immersion Lab on Certifying Algorithms - Winter 2013/14 (MPI Saarbrücken)
