Class RastriginEvaluator

java.lang.Object

pl.edu.agh.age.compute.ea.evaluation.real.RastriginEvaluator

All Implemented Interfaces:

io.vavr.Function1<DoubleVectorSolution,java.lang.Double>, java.util.function.Function<DoubleVectorSolution,java.lang.Double>, Evaluator<DoubleVectorSolution>

public final class RastriginEvaluator
extends java.lang.Object
implements Evaluator<DoubleVectorSolution>

This class represents a floating-point coded Rastrigin function.

Solution: min=0.0, xi=0, i=1..n

The original problem is a minimalization one but it is much convenient to maximize the problem function. So the original function is modified g(x)=-f(x)
