Playing weighted Tron on trees

We consider the weighted version of the Tron game on graphs where two players, Alice and Bob, each build their own path by claiming one vertex at a time, starting with Alice. The vertices carry non-negative weights that sum up to 1 and either player tries to claim a path with larger total weight than the opponent. We show that if the graph is a tree then Alice can always ensure to get at most 1...

Tron, a Combinatorial Game on Abstract Graphs

We study the combinatorial two-player game Tron. We answer the extremal question on general graphs and also consider smaller graph classes. Bodlaender and Kloks conjectured in [2] PSPACEcompleteness. We proof this conjecture.

Espaces de représentation multidimensionnels dédiés à la visualisation

Résumé. Dans un système décisionnel, la composante visuelle est importante pour l’analyse en ligne OLAP. Dans cet article, nous proposons une nouvelle approche qui permet d’apporter une solution au problème de visualisation des données engendré par l’éparsité. En se basant sur les résultats d’une analyse des correspondances multiples (ACM), nous tentons d’atténuer l’effet négatif de l’éparsité ...

TrOn: An Anatomical Ontology for the Beetle Tribolium castaneum

In a morphological ontology the expert's knowledge is represented in terms, which describe morphological structures and how these structures relate to each other. With the assistance of ontologies this expert knowledge is made processable by machines, through a formal and standardized representation of terms and their relations to each other. The red flour beetle Tribolium castaneum, a represen...
