On the number of higher order Delaunay triangulations
Dieter Wilhelm, Mitsche; Saumell Mendiola, Maria; Silveira, Rodrigo Ignacio (Springer Verlag, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialHigher order Delaunay triangulations are a generalization of the Delaunay triangulation which provides a class of well-shaped triangulations, over which extra criteria can be optimized. A triangulation is order-k Delaunay ... -
Proximity graphs inside large weighted graphs
Ábrego, Bernardo M.; Fabila Monroy, Ruy; Fernández-Merchant, Silvia; Flores Peñaloza, David; Hurtado Díaz, Fernando Alfredo; Meijer, Henk; Sacristán Adinolfi, Vera; Saumell Mendiola, Maria (2010)
Text en actes de congrés
Accés obertGiven a large weighted graph G = (V;E) and a subset U of V , we de¯ne several graphs with vertex set U in which two vertices are adjacent if they satisfy some prescribed proximity rule. These rules use the shortest path ... -
Recoloring directed graphs
Felsner, Stefan; Huemer, Clemens; Saumell Mendiola, Maria (Prensas Universitarias de Zaragoza, 2009)
Text en actes de congrés
Accés obertLet G be a directed graph and k a positive integer. We define the k-color graph of G (Dk(G) for short) as the directed graph having all k-colorings of G as node set, and where two k-colorings and ' are joined by a ... -
Some properties of higher order delaunay and gabriel graphs
Bose, Prosenjit; Collette, Sébastien; Hurtado Díaz, Fernando Alfredo; Korman, Matias; Langerman, Stefan; Sacristán Adinolfi, Vera; Saumell Mendiola, Maria (2010)
Text en actes de congrés
Accés obertWe consider two classes of higher order proximity graphs defined on a set of points in the plane, namely, the k-Delaunay graph and the k-Gabriel graph. We give bounds on the following combinatorial and geometric properties ... -
Terrain prickliness: theoretical grounds for high complexity viewsheds
Acharyya, Ankush; Jallu, Ramesh; Löffler, M.; Meijer, Geert; Saumell Mendiola, Maria; Silveira, Rodrigo Ignacio; Staals, Frank (2021)
Text en actes de congrés
Accés obertAn important task when working with terrain models is computing viewsheds: the parts of the terrain visible from a given viewpoint. When the terrain is modeled as a polyhedral terrain, the viewshed is composed of the union ... -
Terrain prickliness: theoretical grounds for low complexity viewsheds
Acharyya, Ankush; Jallu, Ramesh; Löffler, M.; Meijer, Geert; Saumell Mendiola, Maria; Silveira, Rodrigo Ignacio; Staals, Frank; Tiwary, Hans Raj (2021)
