    The Complexity of Cluster Vertex Splitting and Company

    Clustering a graph when the clusters can overlap can be seen from three different angles: We may look for cliques that cover the edges of the graph with bounded overlap, we may look to add or delete few edges ...

    The Complexity of Routing Problems in Forbidden-Transition Graphs and Edge-Colored Graphs

    The notion of forbidden-transition graphs allows for a robust generalization of walks in graphs. In a forbidden-transition graph, every pair of edges incident to a common vertex is permitted or forbidden; a walk ...

    The Minimum Feasible Tileset Problem

    We introduce and study the Minimum Feasible Tileset problem: given a set of symbols and subsets of these symbols (scenarios), find a smallest possible number of pairs of symbols (tiles) such that each scenario ca...

    Algorithms and Experiments for Clique Relaxations—Finding Maximum s-Plexes

    We propose new practical algorithms to find degree-relaxed variants of cliques called s-plexes. An s-plex denotes a vertex subset in a graph inducing a subgraph where every vertex has edges to all but at most s v...
