(Reported to unkwown date) The Bron-Kerbosch algorithm with vertex ordering is output sensitive.

-- George Manoussakis (University of Versailles)

summary: The Bron-Kerbosch algorithm is a well known maximal clique enumeration algorithm. So far it was unknown whether it was output sensitive or not. In this paper we partially answer this question by proving that the Bron-Kerbosch Algorithm with vertex ordering, first introduced and studied by Eppstein, Löffler and Strash ...


L-orientations of graphs

-- Kenta Ozeki (Yokohama National University)

summary: An orientation of an (undirected) graph G is an assignment of directions to each edge of G. In this talk, we consider an orientation such that the out-degree of each vertex is contained in a given list. We introduce several relations to graph theory topics and pose our main ...

PHD defense: A guide book for the traveller on graphs full of blockages

-- Pierre Bergé (LRI, University of Paris Saclay)

summary: We study NP-hard problems dealing with graphs containing blockages.

We analyze cut problems via the parameterized complexity framework. The size p of the cut is the parameter. Given a set of sources {s_1,...,s_k} and a target t, we propose an algorithm deciding whether a cut of size at ...

Optimal curing policy for epidemic spreading over a community network with heterogeneous population

-- Francesco De Pellegrini (University of Avignon)

summary: The design of an efficient curing policy, able to stem an epidemic process at an affordable cost, has to account for the structure of the population contact network supporting the contagious process. Thus, we tackle the problem of allocating recovery resources among the population, at the lowest cost possible ...
