Clique partitioning with value-monotone submodular cost
(Elsevier, 2015)
We consider the problem of partitioning a graph into cliques of bounded cardinality. The goal is to find a partition that minimizes the sum of clique costs where the cost of a clique is given by a set function on the nodes. ...
Finding archetypal patterns for binary questionnaires
One of the main challenges researchers face is to identify the most relevant features in a prediction model. As a consequence, many regularized methods seeking sparsity have flourished. Although sparse, their solutions may ...
Topological design of Wireless sensor network: Formulations and exact algorithms
(Universidade Federal de Minas GeraisUFMG, 2018-08-31)
The subject of this thesis is the design of Wireless Sensor Networks (WSN). Given a limited set of sensors and a single sinks, we are particularly interested in the topological WSN design problem. This problem consists in ...

Algorithms for symmetric submodular function minimization under hereditary constraints and generalizations
(SIAM publications, 2013)
We present an efficient algorithm to find nonempty minimizers of a symmetric submodular function f over any family of sets I closed under inclusion. Our algorithm makes O(n(3)) oracle calls to f and I, where n is the ...
