algs.model.data.points.UnusualGenerator
public class UnusualGenerator
Divide the size into n/4 and create uniform clusters of [0,1] way apart along the +/- X-axis and Y-axis. This data set tests the way how errors caused by floating point arithmetic can alter the result of an algorithm
Field Summary | |

Generator<IPoint> |
construct(java.lang.String[] args)
Provide reflective behavior to construct instance of generator given an array of string arguments. |
IPoint[] |
generate(int size)
Generate a set of |size| points all clustered into four regions, each located at the corners of a rectangle of width and height of maxValue. |
java.lang.String[] |
parameters()
Declares the name of the parameters used when constructing the generator in order from left to right. |
