The difference between AI and theoretical computer science is that the former deals with heuristics while the latter requires provable guarantees.
So is it harder to come up with good heuristics than it is to come up with provable guarantees (for presumably simpler problems)?
It's hard to say.
There are theoreticians who dabble in AI of course, complicating things even more:

That really wasn't the point of course.
And AI deals with rather a bit more than heuristics. e.g. The particular subject I'm writing my thesis on is a theorem prover; pure logical reasoning.
And if one were to write a program that can automatically prove the validity of programs; that would be AI applied to theoretical computer science.

Theorem provers generally employ heuristics. The problem addressed is usually undecidable.

Theorem provers also generally have provably correct results; which is rather the point. So any 'heuristic' that is used cannot be allowed to introduce any uncertainty about correctness of the result.
If you find a proof, the proof must be correct; if you find there isn't a proof, there mustn't be; if you can't decide within reasonable time, you don't.

Evaluation though cannot consist of only proofs (as in theory). You need to measure performance using experiments.
Ensuring correctness may of course require some non-trivial proofs.

That holds for every applied science.
Theoretical computer science may give wonderful algorithm with great theoretical time complexity that when applied are entirely worthless in any real situation.
And also AI, like CS, isn't necessarily applied; there is a lot of theoretical work being done (like inventing logics and protocols).

I think it would be important to figure out how a person with high IQ (we are as yet to define IQ without bias) got the way he/she is now. My imaginative/visual brain tells me as a person growsn and learns he develops a neural pathway, kind of like a cache line/circuit in microprocessor .. dynamic ain't it? ... witht that and his personal physiology will dictate how many pathways the person can accomodate and how fast can he generate/retain those.. like the speed of the processor ... anyways.. this will ultimately result in a fast thinking creative indivdual who we perceive as a high IQ person. Now where have I heard this before.. yes.. I think this does apply to AI/neural/fuzzy logic and if we come up with a good adaptive model (as I suggested before) ... we should have a good ranking algorithm!!!

On a related note: when I googled "Cyclotomic Polynomial" (an important concept in number theory), I expected the articles from Mathworld and Wikipedia to get very high ranks. The latter is indeed the first, but where is the former?..

http://mathworld.wolfram.com/CyclotomicPolynomial.html ?
Or do you mean amongst google's results?

I notice that lot of results are from .edu website.. Maybe google does give them a higher rank than wolfram?
THere was one thing to mention on that. Long time ago I had opened up my website on a freeserver. I wouldn't see that on the top of google results. So in order to improve it I added the site to google groups and such... and voila it was number 1 in my search result. Now, I used to update it regularly and it stayed on the top, but slowly it started showing results for me and people with similar name from edu site on higher rank. As for e.g. a website with my name on a paper in the citations would show up higher than my website. Lately I haven't updated my website at all as I feel very bored in doing so.. my information is at least 2 years outdated... the result appears now somewhere way down...
