C# Class SharpNeat.DistanceMetrics.DistanceMetricUtils

Static helper methods for distance metrics.

Public Methods

Method	Description
CalculateCentroid ( IDistanceMetric distanceMetric, IList coordList ) : CoordinateVector	Calculates a centroid by comparing each coordinate with every other coordinate. The coord with the lowest average distance from all other coords is the most central coord (the centroid). This method uses an inefficient N*N comparison of coords to find a centroid. It is provided only as a last resort for distance metrics for which no means exist to calculate a centroid more directly.

Private Methods

Method	Description
CalculateMeanDistanceFromCoords ( IDistanceMetric distanceMetric, IList coordList, int idx ) : double	Calculate the mean distance of the specified coord from all of the other coords using the provided distance metric.
