String Graph Obstacles of High Girth and of Bounded Degree
Maria Chudnovsky, David Eppstein, David Fischer
A string graph is the intersection graph of curves in the plane. Kratochvíl previously showed the existence of infinitely many obstacles: graphs that are not string graphs but for…
Entropy-Bounded Computational Geometry Made Easier and Sensitive to Sortedness
David Eppstein, Michael T. Goodrich, Abraham M. Illickan +1
We study entropy-bounded computational geometry, that is, geometric algorithms whose running times depend on a given measure of the input entropy. Specifically, we introduce a meas…
Better Late than Never: the Complexity of Arrangements of Polyhedra
Boris Aronov, Sang Won Bae, Sergio Cabello +4
Let be the subdivision of induced by convex polyhedra having facets in total. We prove that has combinatorial complexity $O(m^{\l…
Bandwidth vs BFS Width in Matrix Reordering, Graph Reconstruction, and Graph Drawing
David Eppstein, Michael T. Goodrich, Songyu Liu
We provide the first approximation quality guarantees for the Cuthull-McKee heuristic for reordering symmetric matrices to have low bandwidth, and we provide an algorithm for recon…
