Nothing Like Checking Into a Nice Hotel Room and Signing a Bill for $0

I've been working on a problem in Number Theory off and on for almost
ten years called "the Collatz Conjecture" aka "the 3X + 1 problem".
Let f(x) be a function defined on the positive integers such that:

f(x) = x/2 if x is even
f(x) = (3*x+1)/2 if x is odd

Then the conjecture is: iterates of f(x) will eventually reach 1 for any
initial value of x. Various cash prizes have been offered for the proof or disproof of this conjecture.
