Method Detail

valueOf

public abstract double valueOf(double[] x)

Specified by:

valueOf in interface IObjectiveFunction

Parameters:

x - a point (candidate solution) in the pre-image of the objective function

Returns:

objective function value of the input search point

valuesOf

public double[] valuesOf(double[][] pop)

Specified by:

valuesOf in interface IObjectiveFunctionParallel

Parameters:

pop - is an array of search points to be evaluated, where pop[i] is the i-th point.

Returns:

array of objective function values. The i-th value is the objective function value of pop[i].

isFeasible

public boolean isFeasible(double[] x)

Specified by:

isFeasible in interface IObjectiveFunction
