Method Details

initialize

public void initialize(Algorithm algorithm)

Description copied from interface: TerminationCondition

Invoked when the algorithm is created to collect any initial conditions. Note that the algorithm may not have been initialized at this point.

Specified by:

initialize in interface TerminationCondition

Parameters:

algorithm - the algorithm

shouldTerminate

public boolean shouldTerminate(Algorithm algorithm)

Description copied from interface: TerminationCondition

Invoked after every step to check if the algorithm should terminate.

Specified by:

shouldTerminate in interface TerminationCondition

Parameters:

algorithm - the algorithm

Returns:

true if the algorithm should terminate; false otherwise
