Removed questionable prize offered by a Japanese AI firm, and added a more reliable prize by Tim Roberts.

Dec 20, 2016 at 19:41 comment added skan I like the Collatz Conjecture because anybody can understand it.
Jan 24, 2014 at 13:31 comment added Per Alexandersson Zeilberger recently put $500 in a donation to the OEIS if a part of Collatz conjecture is solved, see arxiv.org/abs/1401.1532
May 28, 2011 at 5:49 comment added Gerry Myerson @Daniel, ordinarily I'd say, if Lagarias says so, it must be true, but I'm disappointed that he doesn't give any reference.

May 27, 2011 at 23:06 comment added Gerry Myerson @Daniel, I'm afraid changing Hungarians hasn't made matters any better. Erdos offered money for his own problems, not for those of other people. Despite what the "informal references" may say, I'd be deeply surprised if Erdos offered anything for settling the Collatz problem.

May 27, 2011 at 14:09 comment added Steven Gubkin 500 double dollars. I feel like I just walked into a trigun episode.
May 27, 2011 at 9:45 comment added Mark Bell As the conjecture is stated, False as $\forall N$, $T^N(2^{N+1}) = 2 \neq 1$ but I doubt I'll get \$500 for stating that.
May 27, 2011 at 5:41 comment added Gerry Myerson The statement is not correct as $N$ must be allowed to depend on $n$. Is there documentation for Halmos' offer? Did the offer expire with the professor? Not that I expect anyone to collect on it any time soon....
