public boolean isFinished()

isFinished

Stop search after a number of iterations

Returns:

a boolean.

searchFinished

public void searchFinished(GeneticAlgorithm<?> algorithm)

Called after the last iteration

Specified by:

searchFinished in interface SearchListener

Overrides:

searchFinished in class StoppingConditionImpl

Parameters:

algorithm - a GeneticAlgorithm object.

reset

public void reset()

Returns:

a long.

forceCurrentValue

public void forceCurrentValue(long value)

Force a specific amount of used up budget. Handle with care!

Parameters:

value - The new amount of used up budget for this StoppingCondition
