    • A fix-and-relax heuristic for controlled tabular adjustment 

      Baena, Daniel; Castro Pérez, Jordi (2013-07)
      Research report
      Open Access
      Controlled 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 ...

    • Fix-and-relax approaches for controlled tabular adjustment 

      Baena, Daniel; Castro Pérez, Jordi; González Alastrué, José Antonio (2015-06-01)
      Article
      Open Access
      Controlled 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 ...

    • On using an improved Benders method for cell suppression 

      Baena, Daniel; Castro Pérez, Jordi; Frangioni, Antonio (2017)
      Conference report
      Open Access
      The cell suppression problem (CSP) is one of the most widely applied methods for tabular data protection. Given a set of primary cells to be protected, CSP aims at finding a set of secondary cells to be additionally removed ...

    • Stabilized Benders methods for large-scale combinatorial optimization, with application to data privacy 

      Baena, Daniel; Castro Pérez, Jordi; Frangioni, Antonio (2020-07)
      Article
      Open Access
      The Cell Suppression Problem (CSP) is a very large Mixed-IntegerLinear Problem arising in statistical disclosure control. However, CSPhas the typical structure that allows application of the Benders de-composition, which ...

    • Stabilized Benders methods for large-scale combinatorial optimization, with appllication to data privacy 

      Baena, Daniel; Castro Pérez, Jordi; Frangioni, Antonio (2017-10-24)
      Research report
      Open Access
      The Cell Suppression Problem (CSP) is a challenging Mixed-Integer Linear Problem arising in statistical tabular data protection. Medium sized instances of CSP involve thousands of binary variables and million of continuous ...

    • Symmetric vs asymmetric protection levels in SDC methods for tabular data 

      Baena, Daniel; Castro Pérez, Jordi; González Alastrué, José Antonio (Springer, 2018-09)
      Article
      Open Access
      Protection levels on sensitive cells—which are key parameters of any statistical disclosure control method for tabular data—are related to the difficulty of any attacker to recompute a good estimation of the true cell ...

    • Using a Mathematical Programming Modeling Language for Optimal CTA 

      Castro Pérez, Jordi; Baena, Daniel (Springer Berlin / Heidelberg, 2008-09-30)
      Part of book or chapter of book
      Restricted access - publisher's policy
      Minimum-distance controlled tabular adjustment methods (CTA) have been formulated as an alternative to the cell suppression problem (CSP) for tabular data. CTA formulates an optimization problem with fewer variables and ...
