Method Details

compute

public double compute(double[] vector,
 double[] weightVector,
 IdealPoint idealPoint,
 NadirPoint nadirPoint)

Computes the Tschebyscheff aggregation function using the formula: max(|vector[n] - idealPoint.value(n)| * weightVector[n]). If weightVector[n] is equal to 0, feval is set to 0.000001 * diff.

Specified by:

compute in interface AggregationFunction

Parameters:

vector - The input vector to be aggregated.

weightVector - The weight vector to be used in the aggregation.

Returns:

The result of the Tschebyscheff aggregation function.

epsilon

public void epsilon(double epsilon)

Specified by:

epsilon in interface AggregationFunction

normalizeObjectives

public boolean normalizeObjectives()

Specified by:

normalizeObjectives in interface AggregationFunction
