i'm back

And so I'm back. ICT didn't turn out that badly, although one NSF almost killed me.

It was good to see all the familiar faces, including people who ORD before us. At least half the platoon were the same bunch of people whom I've worked with for more than a year and we all ended up in our usual nonesense. Okay, ICT was good compared to NS days. I think the reason is that the only regular in the unit is CO and there was no such thing as fall-in that kind of regimentation.

I must say I've learnt a lot about weiqi (or Go) in this ICT by watching people play and by playing. It is actually a very interesting game.

9 more to go. Next year will be high key.

Oh yes I got an email from facebook while I was in ICT.

Hi Victor,

I wanted to see if you might be interested in exploring opportunities at Facebook. Your strong coding performance on Topcoder is highly regarded at Facebook. We’re growing fast, and we’re looking for someone to play an instrumental role in our growth and development. Considering your background you would be an excellent fit.

Facebook seems more popular than I realized - it could be quite an opportunity. May the code be with you! Kind regards, bitRAKE.

My email is at gmail.com

Currently, I am coding x86-64 versions of the algorithms outlined in, Prime Numbers - A Computational Perspective by Richard Crandall and Carl Pomerance. Once I get a few together I'll begin posing on my Google Group page: http://groups.google.com/group/bitRAKE

Thank you for the gracious offer: I would enjoy working together - something online that we could spread over a few years would work best for me. Anything which helps expand my understanding of number theory is entertaining enough to hold my attention.

If you could write a general equation for the speed bits travel in the Collatz problem as time approaches infinity then it is solved. :D We know the limit converges for each input number, but how to reduce the algorithm generating the limit equation is where the difficulty is.

My technique moves the problem back to an infinite number line rather than a branching space. So, all we need to prove is that the limit converges to a real value.

That is where I'm stuck presently, but I can quickly reduce million+ digit numbers, and I've got some notes which might allow me to finally surpass the data driven algorithm.
