Method Detail

init

public void init(Blackboard blackboard)

Initialises the FinalJudge object. Call this method before starting evolution of evaluable expressions to start counting the total time the entire evolution of evaluable expressions takes.

Parameters:

blackboard - The Blackboard to store the data of this FinalJudge on. Must not be null.

judge

public boolean judge(Blackboard blackboard)

Implements the break condition for evolution of evaluable expressions. Decides whether evolution will be continued or stopped depending on the fitness of the fittest evaluable expression, the number of generations passed, the time passed, and the relative improvement of a generation.

Parameters:

blackboard - The Blackboard this FinalJudge operates on. Must not be null.

Returns:

true to indicate that evolution of evaluable expressions will be stopped; false otherwise.
