Method Detail

stepOn

public io.vavr.collection.List<DoubleVectorSolution> stepOn(long stepNumber,
                                                            io.vavr.collection.List<DoubleVectorSolution> population)

Description copied from interface: Step

Method invoked during each iteration. Make sure that a minimum number of operations is executed here.

Specified by:

stepOn in interface Step<DoubleVectorSolution>

Parameters:

stepNumber - the current step number

population - the current population

Returns:

the new population - a result of step iteration calculations
