With N=10 I have many iterations lower than[*] (I have an "outlier" too:[*] !!!!)

[*] Admin Edit: I have masked the specific numbers since they reveal too much about the answer. Please start a thread whose title starts with *ANSWER* to discuss this per the announcement.

I suggest starting an *ANSWER* thread and discussing this openly with other participants.

everyone is cool
and here is mine

The most exciting thing is that after 1000 iteration, I get almost exactly the answer, with differences 0.6 and 3 in average iteration respectively for N = 10 and 100.

Admin edit: I am guessing this is the wrong jpg, so please let me know the right one and I'll edit it in.

Here's my attempt at an animation using Python and matplotlib with N=100: http://dl.dropbox.com/u/153/hw/problem_9.html.

Thanks for pointing problem 1.3 in the book.
I have ordered it, but not received it yet. I will have a look.

Thanks @pyguy !! That was very cool! I would love to see how you did that -- any chance you can share your code? I want to learn! Many thanks!

Sorry about that. I'll be more careful...
