Constructor Summary

SelectionMethods()

Method Summary

static void	selectBest(double[] values, int valuesSize, int order, int[] sample, int sampleSize) places in the sample array, sampleSize indices of the elements in values that contain the best values corresponding to an ascending order if order is 1 or to a descending order otherwise
static void	selectProb(int N, double[] probabilities, int[] sample, int n, java.util.Random rand) selects n integers between 0 and N-1 based on their probabilities; places the selected integers in sample; probabilities should be cumulative probabilities
static void	selectUnif(int N, int[] sample, int n, java.util.Random rand) selects n integers with uniform probability, between 0 and N - 1 and places the selected values in the field sample
