These are the two cell suppresssion instances generators used in some Jordi Castro's papers. The instances are written following the syntax of the AMPL modelling language. The format for two-dimensional tables is straightforward. For two-dimensional hierarchical tables, a description of the table structure can be found in this technical report . Look at the first lines of the code for details about the input parameters for each generator.
To install the generators, download the .zip files, "unzip" them, go to the directory that is created, and run "make" (Unix/Linux systems). In other systems, compile the ".cpp" file.
