Stabbing simplices of point sets with k-flats
(2013)
Let S be a set of n points in Rd in general position. A set H of k-flats is called an mk-stabber of S if the relative interior of any m-simplex with vertices in S is intersected by at least one element of H. In this paper ...

Computing the stretch of an embedded graph
(2013)
Let G be a graph embedded in an orientable surface Σ, possibly with edge weights, and denote by len(γ) the length (the number of edges or the sum of the edge weights) of a cycle γ in G. The stretch of a graph embedded on ...

Metaheuristic approaches for the minimum dilation triangulation problem
(2013)
We focus on the development of approximated algorithms to find high quality triangulations of minimum dilation because the complexity status of the Minimum Dilation Triangulation problem for a general point set is unknown. ...
