usage: java -cp <jar> br.ufpr.inf.cbio.hhco.runner.HHCORunner [-h] [-id
       <id>] [-m <objectives>] [-p <problem>] [-P <path>] [-s <seed>]

Execute a single independent run of the HHCO algorithm on a given
<problem>.
 -h,--help                      print this message and exits.
 -id <id>                       set the independent run id, default 0.
 -m,--objectives <objectives>   set the number of objectives (default
                                value is 5).
 -p,--problem <problem>         set the problem instance: MaF[1-15],
                                default MaF01
 -P,--output-path <path>        directory path for output (if no path is
                                given experiment/ will be used.)
 -s,--seed <seed>               set the seed for JMetalRandom, default
                                System.currentTimeMillis()
