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

    Baena, Daniel; Castro Pérez, Jordi (2013-07)
    External 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 ...
