Why it gives different result if I shuffle the sample data?

[jackiemiao1107]

the origin data gives the result:

Iteration 5/100
	 AFTER: length of cluster 0 => 1307
	 AFTER: length of cluster 1 => 3816
	 AFTER: length of cluster 2 => 3360
	 AFTER: length of cluster 3 => 7067
	 AFTER: length of cluster 4 => 616
	 AFTER: length of cluster 5 => 761
	 AFTER: length of cluster 6 => 865
	 AFTER: length of cluster 7 => 815

but if I shuffle the data in data.txt, it gives:

Iteration 5/100
	 AFTER: length of cluster 0 => 20
	 AFTER: length of cluster 1 => 20
	 AFTER: length of cluster 2 => 20
	 AFTER: length of cluster 3 => 18467
	 AFTER: length of cluster 4 => 20
	 AFTER: length of cluster 5 => 20
	 AFTER: length of cluster 6 => 20
	 AFTER: length of cluster 7 => 20

why?
