LATIN2016

Our paper “Listing Acyclic Orientations of Graphs with Single and Multiple Sources” has been accepted to be published at Latin American Theoretical Informatics Symposium, LATIN 2016 to be held in Ensenada, Mexico (April 11-15, 2016). The abstract follows. We study enumeration problems for the acyclic orientations of an undirected graph with n nodes and m[…]

IWOCA2015

Our paper about “Enumerating Cyclic Orientations of a Graph” will be presented at IWOCA2015 in Verona! Thanks to all my coauthors: Alessio Conte, Roberto Grossi, Romeo Rizzi. The abstract follows. Acyclic and cyclic orientations of an undirected graph have been widely studied for their importance: an orientation is acyclic if it assigns a direction to each edge[…]

Our paper “On Computing the Hyperbolicity of Real-World Graphs” has been accepted for ESA 2015 !!! Thanks to all my coauthors Michele Borassi, David Coudert, and Pierluigi Crescenzi. You can read the abstract here. The (Gromov) hyperbolicity is a topological property of a graph, which has been recently applied in several different contexts, such as the design of[…]
