Method Detail

start

void start(Configuration a_config)

Called just before the evolution starts. Setup your monitor here.

Parameters:

a_config - the configuration used

Since:

3.4.4

nextCycle

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

Called after another evolution cycle has been executed.

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

event

void event(java.lang.String a_monitorEvent,
           int a_evolutionNo,
           java.lang.Object[] a_information)

Called whenever it's worth monitoring.

Parameters:

a_monitorEvent - see constants at top of class
