A branch-and-cut algorithm for the multidepot rural postman problem
(2018-03)
Article
Open AccessThis paper considers the Multidepot Rural Postman Problem, an extension of the classical Rural Postman Problem in which there are several depots instead of only one. The aim is to construct a minimum cost set of routes ... -
A checkpoint/restart directive-based approach
(Universitat Politècnica de Catalunya, 2017)
Master thesis
Open Access
Covenantee: Barcelona Supercomputing CenterExascale platforms require programming models incorporating support for resilience capabilities since the huge number of components they are expected to have is going to increase the number of errors. Checkpoint/restart ... -
A consensus model for Delphi processes with linguistic terms and its application to chronic pain in neonates definition
(2015-10)
Article
Open AccessThis paper proposes a new model of consensus based on linguistic terms to be implemented in Delphi processes. The model of consensus involves qualitative reasoning techniques and is based on the concept of entropy. The ... -
A cryptographic solution for private distributed simple meeting scheduling
(IOS Press, 2009)
Conference report
Open AccessMeeting scheduling is a suitable application for distributed computation motivated by its privacy requirements. Previous work on this problem have considered some cryptographic and conceptually clear approach to solve a ... -
A data-driven learning method for constitutive modeling: application to vascular hyperelastic soft tissues
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-01)
Article
Open AccessWe address the problem of machine learning of constitutive laws when large experimental deviations are present. This is particularly important in soft living tissue modeling, for instance, where large patient-dependent ... -

A fix-and-relax heuristic for controlled tabular adjustment
(2013-07)
Research report
Open AccessControlled tabular adjustment (CTA) is an emerging protect ion technique for tabular data pro- tection. CTA formulates a mixed integer linear programming problem, which is tough for tables of moderate size. Finding a ... -
A genetic algorithm for the mixed flow shop problem

Master thesis
Open Access
Covenantee: Università degli studi di TrentoIn this thesis we present a new interesting version of the mixed flow shop se-quencing problem, which at the same time is a version of the classic flow shop,a very common topic on operations research.We propose a genetic ... -
A heuristic method for a congested capacitated transit assignment model with strategies
(2017-12)
Article
Open AccessThis paper addresses the problem of solving the congested transit assignment problem with strict capacities. The model under consideration is the extension made by Cominetti and Correa (2001), for which the only solution ... -
A Kalman-filter approach for dynamic OD estimation in corridors based on bluetooth and wifi data collection
