Extending Partial Representations of Proper and Unit Interval Graphs
Pavel Klavík, Jan Kratochvíl, Yota Otachi +4
The recently introduced problem of extending partial interval representations asks, for an interval graph with some intervals pre-drawn by the input, whether the partial representa…
Extending Partial Representations of Subclasses of Chordal Graphs
Pavel Klavik, Jan Kratochvil, Yota Otachi +1
Chordal graphs are intersection graphs of subtrees of a tree T. We investigate the complexity of the partial representation extension problem for chordal graphs. A partial represen…
Extending partial representations of function graphs and permutation graphs
Pavel Klavík, Jan Kratochvíl, Tomasz Krawczyk +1
Function graphs are graphs representable by intersections of continuous real-valued functions on the interval [0,1] and are known to be exactly the complements of comparability gra…
MSOL Restricted Contractibility to Planar Graphs
James Abello, Pavel Klavík, Jan Kratochvíl +1
We study the computational complexity of graph planarization via edge contraction. The problem CONTRACT asks whether there exists a set of at most edges that when contracte…
