   * <pre>
   * -P &lt;start set&gt;
   *  Specify a starting set of attributes.
   *  Eg. 1,3,5-7.If supplied, the starting set becomes
   *  one member of the initial random
   *  population.
   * </pre>
   *
   * <pre>
   * -Z &lt;population size&gt;
   *  Set the size of the population (even number).
   *  (default = 20).

   *
   * <pre>
   * -G &lt;number of generations&gt;
   *  Set the number of generations.

   *  Set the probability of crossover.

   * <pre>
   * -M &lt;probability of mutation&gt;
   *  Set the probability of mutation.
   *  (default = 0.033)
   * </pre>
   *
   * <pre>
   * -R &lt;report frequency&gt;
   *  Set frequency of generation reports.
   *  e.g, setting the value to 5 will
   *  report every 5th generation
   *  (default = number of generations)
   * </pre>
