This generator produces random 3D tables to be protected by controlled tabular adjustment. The instances are formulated as saturated convex quadratic separable multicommodity flow problems. Saturated mean that mutual arc capacities are active (i.e., equalities instead of inequalities in the standard multicommodity formulation). The generator produces instances in PPRN format. A description of these instances and the problem solved can be found in J. Castro, Quadratic interior-point methods in statistical disclosure control, Computational Management Science, 2(2) 2005 107-121.

To install the generators, download this file , untar and gunzip it, go to the directory that is created, and run "make all" (Unix/Linux systems). In other systems, compile the source files.
