Caterpillars Have Antimagic Orientations
Antoni Lozano
An antimagic labeling of a directed graph with arcs is a bijection from the set of arcs of to such that all oriented vertex sums of vertices in are…
Antimagic Labelings of Caterpillars
Antoni Lozano, Mercè Mora, Carlos Seara
A -antimagic labeling of a graph is an injection from to such that all vertex sums are pairwise distinct, where the vertex sum at vertex …
Fast calculation of entropy with Zhang's estimator
Antoni Lozano, Bernardino Casas, Chris Bentz +1
Entropy is a fundamental property of a repertoire. Here, we present an efficient algorithm to estimate the entropy of types with the help of Zhang's estimator. The algorithm takes…
Distinguishing Tournaments with Small Label Classes
Antoni Lozano
A -distinguishing vertex (arc) labeling of a digraph is a vertex (arc) labeling using labels that is not preserved by any nontrivial automorphism. Let () be th…
