No change at all. Same clusters from iteration to iteration.

You don't need a lot of runs or a lot of test points to get good results
My tests took ~3 minutes per test (you only need 3) and gave me the good answers for that part of the final.

Each data set has 100 entries. I run the test 500 times, each creating a new training and test data set. I compute a new set of centroids for each new new training set. Then evaluate the result.

What is the tolerance between two Eins or 2 Eout whether they are the same?
