Wolfram Offers Prize For (2,3) Turing Machine

An anonymous reader writes "Stephen Wolfram, creator of Mathematica and author of A New Kind of Science, is offering a prize of $25K to anyone who can prove or disprove his conjecture that a particular 2-state, 3-color Turing machine is universal. If true, it would be the simplest universal TM, and possibly the simplest universal computational system. The announcement comes on the 5-year anniversary of the publication of NKS, where among other things Wolfram introduced the current reigning TM champion — 'rule 110,' with 2 states and 5 colors."

However, there is no guarantee that each starting state will reach a unique final one. So by observing the final state we cannot always uniquely determine the starting state.

      I'm not convinced that that is a valid conclusion. There are many systems (such as chaotic systems) that are entirely deterministic but also entirely non-predictable. The two states are not mutually exclusive. It is entirely possible that the result of any given collision of particles is 100% deterministic, but that because we cannot measure the initial conditions, we cannot predict what the result would be.

      An alternative view is that when you talk about a "probability" in quantum mechanics, you are really talking about the fraction of the wave function that describes something that exists in the state you are considering the probability for. In that case, all possible outcomes occur, but you only see the dominant one. (This is slightly better than the "many worlds" theory, in that it doesn't require the spontaneous creation of universes.) Here, there are not really "different outcomes", just different ratios, which may or may not be deterministic. This interpretation allows for "randomness", but in a different sense than is normally considered, but could also be treated as a chaotic system.

      A third view is the "many worlds" theory. Since every possibility is mapped out into a gigantic n-ary tree of possibilities, it is entirely valid to say that every given path is fixed and that the tree is static. What varies is the path you take through it. Is that a fixed future or not? The path you take isn't fixed, but the result of whatever path you do take is.

      Personally, I dislike the "many worlds" theory, it smacks too much of Fred Hoyle's "October the First Is Too Late". Ugh. Ghastly. Since the second option can be treated as chaos theory, it's really just a minor variant of the first. In either case, the future would indeed be entirely predetermined but it would also be unknowable.

      Is that likely? Well, does it matter? If the future is not knowable, under the constraints of chaos, it is utterly unimportant for any practical purposes as to whether it is fixed. It may be interesting to know, but it's really not useful - either experimentally or experientially. The only value would be that some probabilities in QM may be replaceable by the corresponding set of Strange Attractors and chaotic systems. However, even if you could do that, unless this led to a simpler model, there really wouldn't be any point. If probabilities are a simpler way to describe things and produce the same results, then whether it is mechanically correct or not, it is the best way to describe things.

      Every fork in the tree represents a random quantum event. If you follow the tree from root to leaf, moving forward in time, there's no way to predict where you'll end up. But if you follow it from leaf to root, there's only one path. The universe is deterministic in reverse.

      The strange thing about Turing machines is they're deterministic in the other direction, from root to leaf - they move forwards in time, but they destroy information, because the output of a calculation has less entropy than the inputs. If you multiply two numbers there's only one possible product. But the product has at least one pair of factors. So there are more input states than output states - the calculation reduces entropy. Think of the inputs as branches of the tree, and the output as the fork where the branches meet (or part). The calculation moves from leaf to root, but meanwhile the machine doing the calculation moves forward in time, from root to leaf. So a Turing machine is like a mirror: it shows you a little world, but it's a world where everything is reversed.

(The fact that that disproof was brought to public notice by the NKS Forum moderator might suggest that the ongoing NKS project is happy enough for results to fall whichever way they will.)

    On a visit to Champaign-Urbana in the late 1980s, still before he officially started on NKS, Wolfram took me through where he felt his cellular automata research was headed which hinted at some of the inferences he would eventually draw from his mountains of research data. That was even before the Santa Fe Institute paper which was foolishly read as retreating from the edge of chaos-border of order which had briefly been the focus of the quest for the source of emergent complexity during the 1980s.

    The resources Wolfram is bringing to the table are significant and have certainly helped put complex systems back in the spotlight after far too many of the first generation of researchers were seduced by the marginal returns they could get by applying their methods to the derivatives market, no matter whether their methods made a significant difference or not.

    The downside of continuing to focus on the simplest possible mechanisms (Wolfram calls them 'programs') as the source of a critical threshold is that all those much sought after proofs of universality, from the early one for Conway's Life on, are vast feats of engineering and thus make no useful progress towards the implicit goal of helping to explain how we/anything got here in the first place.

    Maybe I've been spoiled by the cellular automata rules in the (Martin Conway) game of Life, and maybe because of that I don't get this. At least, that's what I am trying to understand, is he saying that eventually the set of rules for these two states have a particular sequence that repeats, so that no matter what state it is in, eventually it will cycle to that state again, or what?

    Someone - it might be Kurt Vonnegut - once stated that anyone who can't explain what they are doing to a six-year-old is a fraud.

Programmers - like myself - are exceptionally good at puzzles, and some - again, like myself (no false modesty here) - are fairly bright and are willing to take on a challenge, the problem is that we as problem solvers have to be able to understand the problem in order to solve it.

    I think either he needs to explain what he wants to solve better, or he needs to hire someone bright who can translate what he is trying to determine to others so they can understand it. I think, were he to provide a better explanation of what he is interested in discovering, he'd have a better chance of getting people to try and solve it. This presumes he actually wants a solution and that this is not some advertising scheme to sell more of his books. (If that were the case, he'd really need to throw more money at it. He could always rig the rules such that you can't really win.) But since you could read them on-line I don't see where that's all that much of an issue.

But he definitely needs to find a way to explain it better if he actually wants it solved, or throw more money at it in order to make people smell blood.
