ChainedMonitors(java.util.List<IEvolutionMonitor> a_monitors, int a_positiveMonitorsRequired)

Method Summary

boolean	nextCycle(Population a_pop, java.util.List<java.lang.String> a_messages) Called after another evolution cycle has been executed.
void	start(Configuration a_config) Called just before the evolution starts.

Constructor Detail

ChainedMonitors

public ChainedMonitors(java.util.List<IEvolutionMonitor> a_monitors,
                       int a_positiveMonitorsRequired)

Parameters:

a_monitors - sequence of monitors to use

a_positiveMonitorsRequired - number of monitors that must return true in nextCycle in order to let the evolution continue. If this parameter equals one, it means we have an or-operation, if it equals the number of monitors, we have an and-operation.

Since:

3.4.4

Method Detail

nextCycle

public boolean nextCycle(Population a_pop,
                         java.util.List<java.lang.String> a_messages)

Called after another evolution cycle has been executed.

Specified by:

nextCycle in interface IEvolutionMonitor

Parameters:

a_pop - the currently evolved population

a_messages - the monitor can append messages here to indicate why it asks evolution to stop

Returns:

true: continue with the evolution; false: stop evolution

Since:

3.4.4

start

public void start(Configuration a_config)

Called just before the evolution starts.

Specified by:

start in interface IEvolutionMonitor

Parameters:

a_config - the configuration used
