SelectionStrategyControl (Watchmaker Framework for Evolutionary Computation API 0.7.1)

java.lang.Object
- org.uncommons.watchmaker.swing.SelectionStrategyControl<T>

Type Parameters:

T - A generic type that matches the type associated with the selection strategies.

All Implemented Interfaces:

EvolutionControl
```
public class SelectionStrategyControl<T>
extends Object
implements EvolutionControl
```
An evolution control for selecting between different SelectionStrategy implementations. This control provides a proxy selection strategy that delegates to the currently selected strategy. Using this proxy strategy with an EvolutionEngine means that any change to the combo-box selection is immediately reflected in the selection used by the running evolution engine.

    Parameters:
    
    tournamentProbability - The probability parameter for TournamentSelection.
    
    truncationRatio - The ratio parameter for TruncationSelection.
    
    Returns:
    
    A list of selection strategies.
  - getControl
```
public JComboBox getControl()
