  3. Re:Would there be NP problem ramifications? on A Pair Of Quantum Computing Articles · · Score: 1
    as for the comment about factoring, factoring is an NP-complete problem. go review your theory books.

    I am pretty up-to-date on that. I think you are mistaken about that. Factoring is NP, of course, but whether it is NP-complete is not known.

    Give a reference to prove me wrong

  4. Re:Would there be NP problem ramifications? on A Pair Of Quantum Computing Articles · · Score: 1
    It is known that quantum computers (potentially) can factor number in log n time (as opposed to roughly sqrt(n) time for standard computers).

    However it is not know whther P=NP in terms of quantum computers as factorisation is not known to be NP.

    Also there is no reason to think that quantum computers will be faster or indeed more suitable for most problems than ordinary computers.

  5. Re:Neural Networks can't learn. on Neural Networks In The Home? · · Score: 1
    You are confused about the difference between the neural net as a mathematical model and its computer implementation.

    Mathematically speaking neural network is a function with certsain parameters. Learning is a way to adjust the parameters to fit the function to the actual data.

    Just as with people there is a difference between performing a certain task and learning to do it.

  12. Re:I had my doubts about the P4 and SSE2 in genera on Pentium 4 Re-evaluated, Again (Again) · · Score: 1
    Integer performance is a lot more important for compilers, etc rather than floating point.

    OSes are unlikely to benefit much from SSE optimization. And Athlon is quite a bit faster in integer performance.

    It seems that the only well-designed unit in P4 is its SSE engine. On the other hand it might be more related to high latency of the Rambus memore than to processor design.

    What is scary is how many people agree with the author of the original message (it got moderated to 5).

    So far there has een no demonstrable ill effects from genetically engineered plants. There was that business with butterflies in England, but there is no agreement on it either.

    And how is genetically engineered food different from hevily engineered foods of the past? They used mutagens, radiations and what not to try to find beneficial mutations in the last 50 years.

  14. Re:Tunnel vision on AMD's Secrets Revealed · · Score: 1
    Unfortunately, giving up on x86 binary compatability is still considered to big a risk for PC/MB producers.

    Why is it unfortunate? It would be a huge error to waste billions of lines of code written for x86 just in order to get some theoretical improvement in speed.

    And in any case if you really need serious performance why not get an Alpha? Few people do actual computations and for most it is really unimportant whether the architecture is x86 or not.

    It was a bit of a paper launch to counteract P4. They should become available soon however.

    266 Mhz front side bus does not make much difference in terms of performance however. Mostly the increas is due to DDR memory.

    I think it has to do with SSE optimization. While Pentium benchmarks take advantage of SSE, most Athlon benchmarks don't take advantage of 3Dnow.

    Your numerical program in all likelihood take advantage of neither.

    Also don't forget that Intel has far greater resources to make sure all the compilers, etc are fully optimized.

    Furthermore, scientists seek agreement between their models and the behaviour of reality only because that makes their theories useful as opposed to being merely mathematically interesting.

    It is somewhat surprising that someone who is so thouroughly bored with Kubrick movies took time to watch so many of them.

    You call Kubrick cruel? Nobody is but yourself is forcing his films on you. But if you choose to watch them anyway, that is perhaps you find them worth watching.

    Physics as we know it today really started with Netwon, who lived from 1642-1727, well more than 50 to 75 years. It was an "actual science."

    Actually attributing it to Galileo would probably be more correct. He had pretty good understanding of basic physical concepts.

    I am not sure what you call "an actual science", but I would argue that is comes from the Greeks.
