Constructor Details

CompoundTerminationCondition

public CompoundTerminationCondition(TerminationCondition... conditions)

Constructs a new termination condition based on at least one individual termination condition being satisfied.

Parameters:

conditions - the termination conditions

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

getPercentComplete

public double getPercentComplete(Algorithm algorithm)

Description copied from interface: TerminationCondition

Returns the percentage that this condition is complete, as a value between 0.0 and 100.0. If the percentage can not be determined, returns 0d/0d.

Specified by:

getPercentComplete in interface TerminationCondition

Parameters:

algorithm - the algorithm

Returns:

the percentage completion

iterator

public Iterator<TerminationCondition> iterator()

Specified by:

iterator in interface Iterable<TerminationCondition>
