About the NSGA-II ParetoFile Format

The final Pareto set of designs produced by NSGA-II at the end of optimization is saved in the automatically configured file parameter named ParetoFile.

The first line of the ParetoFile is the header line for the table of parameter values and lists the column names as follows:

RunCounter, Height1, Height2, Height3

The first column is the run number of each design point as it was executed during optimization. The rest of the columns are the design variables, constraints, and objectives used by NSGA-II. The last column is named Penalty and contains the penalty values for each design point. The second line of the file contains multiple occurrences of “18N” and is there for the purposes of compatibility with legacy analysis tools. This line can be safely ignored. The data values of all parameters start at line number three.
