Existence, uniqueness and convergence of the regularized primal-dual central path
Castro Pérez, Jordi; Cuesta Andrea, Jordi (2010-09)
Article
Accés restringit per política de l'editorialIn a recent work [J. Castro, J. Cuesta, Quadratic regularizations in an interior-point method for primal block-angular problems, Mathematical Programming, in press (doi:10.1007/s10107-010-0341-2)] the authors improved one ... -
Exploiting total unimodularity for classes of random network problems
Castro Pérez, Jordi; Nasini, Stefano (2013-07)
Report de recerca
Accés obertNetwork analysis is of great interest for the study of social , biological and technolog- ical networks, with applications, among others, in busines s, marketing, epidemiology and telecommunications. Researchers are ... -
Extending controlled tabular adjustment for non-additive tabular data with negative protection levels
Castro Pérez, Jordi (Institut d'Estadística de Catalunya, 2011)
Article
Accés obertMinimum distance controlled tabular adjustment (CTA) is a recent perturbative methodology for the protection of tabular data. An implementation of CTA was recently used by Eurostat for the protection of European Union ... -
Fix-and-relax approaches for controlled tabular adjustment
Baena, Daniel; Castro Pérez, Jordi; González Alastrué, José Antonio (2015-06-01)
Article
Accés obertControlled tabular adjustment (CIA) is a relatively new protection technique for tabular data protection. CTA formulates a mixed integer linear programming problem, which is challenging for tables of moderate size. Even ... -
Generating conditional uniform random networks by optimization procedures
Nasini, Stefano; Castro Pérez, Jordi (Universidad de La Laguna, 2013)
Text en actes de congrés
Accés obertComplex networks is a recent area of research motivated by the empirical study of realworld networks, such as social relations, protein interaction, neuronal connections, etc. As closed-form probabilistic models of networks ... -
Implementació d'un algorisme primal-dual de punt interior amb fites superiors a les variables
Castro Pérez, Jordi (Institut d'Estadística de Catalunya, 1995)
Article
Accés obertImplementación de un algoritmo primal-dual de punto interior con variables acotadas superiormente. -
Implementación de un algoritmo primal-dual de orden superior mediante el uso de un método predictor-corrector para programación lineal
Castro Pérez, Jordi (Institut d'Estadística de Catalunya, 1998)
Article
Accés obertSe presenta una implementación de un algoritmo primal-dual de punto interior para la solución de problemas lineales. El algoritmo difiere de otros ya existentes (como el implementado en el sistema LoQo) en el hecho de que ... -
Improving an interior-point algorithm for multicommodity flows by quadratic regularizations
Castro Pérez, Jordi; Cuesta, Jordi (2009-07)
Report de recerca
Accés obertOne of the best approaches for some classes of multicommodity flow problems is a specialized interior-point method that solves the normal equations by a combination of Cholesky factorizations and preconditioned conjugate ... -
Improving an interior-point approach for large block-angular problems by hybrid preconditioners
Bocanegra, Silvana; Castro Pérez, Jordi; Oliveira, Aurelio R.L. (2012-07)
Report de recerca
Accés obertThe computational time required by interior-point methods is often domi- nated by the solution of linear systems of equations. An efficient spec ialized interior-point algorithm for primal block-angular proble ms has ...
