Augmenting the power of (partial) MaxSat resolution with extension
Larrosa Bondia, Francisco Javier; Rollón Rico, Emma (AAAI Press, 2020)
Conference lecture
Restricted access - publisher's policyThe refutation power of SAT and MaxSAT resolution is challenged by problems like the soft and hard Pigeon Hole Problem PHP for which short refutations do not exist. In this paper we augment the MaxSAT resolution proof ... -
CBR and MBR techniques: review for an application in the emergencies domain
Merida-Campos, Carlos; Rollón Rico, Emma (2003-06-01)
External research report
Open AccessThe purpose of this document is to provide an in-depth analysis of current reasoning engine practice and the integration strategies of Case Based Reasoning and Model Based Reasoning that will be used in the design and ... -

Decomposing utility functions in Bounded Max-Sum for distributed constraint optimization
Rollón Rico, Emma; Larrosa Bondia, Francisco Javier (Springer, 2014)
Conference report
Open AccessBounded Max-Sum is a message-passing algorithm for solving distributed Constraint Optimization Problems (DCOP) able to compute solutions with a guaranteed approximation ratio. In this paper we show that the introduction ... -

Limited discrepancy AND/OR search and its application to optimization tasks in graphical models
Larrosa Bondia, Francisco Javier; Rollón Rico, Emma; Dechter, Rina (AAAI Press (Association for the Advancement of Artificial Intelligence), 2016)
Conference report
Open AccessMany combinatorial problems are solved with a Depth-First search (DFS) guided by a heuristic and it is well-known that this method is very fragile with respect to heuristic mistakes. One standard way to make DFS more robust ... -
Multi-objective optimization in graphical models
Rollón Rico, Emma (Universitat Politècnica de Catalunya, 2008-11-03)
Doctoral thesis
Open AccessMany real-life optimization problems are combinatorial, i.e. they concern a choice of the best solution from a finite but exponentially large set of alternatives. Besides, the solution quality of many of these problems ... -
New mini-bucket partitioning heuristics for bounding the probability of evidence
Rollón Rico, Emma; Dechter, Rina (2009)
Conference report
Open AccessMini-Bucket Elimination (MBE) is a well-known approximation algorithm deriving lower and upper bounds on quantities of interest over graphical models. It relies on a procedure that partitions a set of functions, called ... -
Semiring-based mini-bucket partitioning schemes
Rollón Rico, Emma; Larrosa Bondia, Francisco Javier; Dechter, Rina (AAAI Press. Association for the Advancement of Artificial Intelligence, 2013)
Conference report
Restricted access - publisher's policyGraphical models are one of the most prominent frameworks to model complex systems and efficiently query them. Their underlying algebraic properties are captured by a valuation structure that, most usually, is a semiring. ...
