BrowserUk has asked for the
wisdom of the Perl Monks concerning the following question:
I'm testing an algorithm involving 2D coordinate pairs. I've been generating random datasets like this:
Which is okay as far as it goes, but being pseudo-random, tends to pretty equally distribute the points throughout the 2D plane.
But the worse case scenarios for the algorithm are when you get a bunch of points grouped in one place and then a few outliers far away. Either in another bunch, or widespread.
I could generate a point; generate a bunch around that point (using a subrange of the coordinate space, and then fully randomly add a few more, b u u t... that doesn't seem kosher.
So, any thoughts on a 'better way'?
