AbstractTerminationCriterion

protected AbstractTerminationCriterion(IConfiguration conf,
                                       org.opt4j.core.optimizer.Population population,
                                       org.opt4j.core.optimizer.Archive archive)

Initializes the termination criteria by supplying it with the configuration object and other needed resources.

Parameters:

conf - - The configuration object.

population - - The current Population

archive - - A reference to the archive

Throws:

RuntimeException - if the configuration object is not fully initialized.
