Visually Assessing 1‐D Orderings of Contiguous Spatial Polygons

open access: yesComputer Graphics Forum, EarlyView.
Abstract One‐dimensional orderings of spatial entities have been researched in many contexts, e.g. spatial indexing structures or visualizations for spatiotemporal trend analysis. While plenty of studies have been conducted to evaluate orderings of point‐based data, polygonal shapes, despite their different topological properties, have received less ...

Statistical disaggregation—A Monte Carlo approach for imputation under constraints

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract Equality‐constrained models naturally arise in problems in which the measurements are taken at different levels of resolution. The challenge in this setting is that the models usually induce a joint distribution which is intractable. Resorting to instead sampling from the joint distribution by means of a Monte Carlo approach is also ...

Longest cycles in vertex‐transitive and highly connected graphs

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract We present progress on three old conjectures about longest paths and cycles in graphs. The first pair of conjectures, due to Lovász from 1969 and Thomassen from 1978, respectively, states that all connected vertex‐transitive graphs contain a Hamiltonian path, and that all sufficiently large such graphs even contain a Hamiltonian cycle.
