readFrontFromFile

public static Solutions readFrontFromFile(java.lang.String filePath)
                                   throws java.lang.Exception

Function that reads a set of solutions from a file.

Parameters:

filePath - File path

Returns:

The set of solutions in the archive.

Throws:

java.lang.Exception

readFrontsFromFile

public static java.util.ArrayList<Solutions> readFrontsFromFile(java.lang.String filePath)
                                                         throws java.lang.Exception

Function that reads N sets of solutions from a file.

Parameters:

filePath - File path

Returns:

The set of solutions in the archive. Each solution set is separated in the file by a blank line.

Throws:

java.lang.Exception

normalize

public static void normalize(java.util.ArrayList<Solutions> setOfSolutions,
                             int dim,
