Resum
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 feasible initial solution may ev en be a challenging task for large instances. On the other hand, end users of tabular data prote ction techniques give priority to fast executions and are thus satisfied in practice with suboptima l solutions. In this work the fix-and- relax strategy...
