Interface SelectionOperator

All Known Implementing Classes:
  TournamentSelection, TruncationSelection

    public interface SelectionOperator

Provides the interface to a selection operator. This allows genomes to be selected for offspring production or elimination.

Method Summary
`EvolutionaryAlgorithm` | `getTrainer()`
`int` | `performAntiSelection(Random rnd, Species species)` Selects an unfit genome.
`int` | `performSelection(Random rnd, Species species)` Selects an fit genome.

Method Detail

### performAntiSelection

    int performAntiSelection(Random rnd,
                             Species species)

  Selects an unfit genome.

  Parameters:
    `rnd` - A random number generator.
    `species` - The species to select the genome from.
  Returns:
    The selected genome.

### getTrainer
