The First Evolving Hardware? 148

Masq666 writes "A Norwegian team has made the first piece of hardware that uses evolution to change its design at runtime to solve the problem at hand in the most effective way. By turning on and off its 'genes' it can change the way it works, and it can go through 20,000 - 30,000 generations in just a few seconds. That same number of generations took humans 800,000 - 900,000 years." The University of Oslo press release linked from the article came out a few days ago; the researchers published a paper (PDF) that seems to be on this same technology at a conference last summer.

          Yeah, it was pretty amazing. They mapped out a section of the circuit that the genetic algorithm came up with and found that when analyzed as a logic circuit, a large portion of the configured part of the FPGA should have had no effect on its behavior. When they cropped that section of the circuit out, though, the rest of it mysteriously stopped working.

          This was because the configured circuit operated a lot of the transistors in linear (i.e., non-saturated) mode, taking advantage of things like parasitic capacitances and induced currents. No sane human would operate an FPGA in this fashion, but since those little anomalies were present, the GA took advantage of them. That's a recurring theme in GA research: if you are running a GA on a simulation, for example, and you have a bug in your simulation code, it's fairly likely that the GA will find and exploit that bug instead of giving you a normal answer. See Karl Sims's research from 1994 for some amusing examples of this.

          Sadly, Xilinx discontinued that particular FPGA line a while back, so if you can't find some old leftovers of that part, you probably won't be able to recreate the experiments yourself (the research was originally done a decade or so ago). This is because that particular device had the advantage of being configurable in a random fashion without risk of burning it out due to things like +V to GND connections. Of course, Xilinx considers their programming interface to be proprietary, so I don't know that you'd be able to recreate that work even if you did manage to find the right part.

    • They've been around for a long time... Send a new bitstream and you change the behavior.

      By using a GA to change the bitstream, you can have evolving hardware. If the GA is itself in the hardware then it is self evolving.

    At first glance, this is supposed to impress us with the hardware:

    By turning on and off its 'genes' it can change the way it works, and it can go through 20,000 - 30,000 generations in just a few seconds. That same number of generations took humans 800,000 - 900,000 years.

    In fact the simplest DNA based organisms/structures (bacteria, virii) have the shortest "life span". The number of generations per sec. isn't anything to brag about.

    All complex organisms have some sort of lifespan longer than a microsecond. For a good reason: people pass on knowledge and adapt *during* their life span (not genetically of course, but our brain allows us to adapt a lot without such).

    Hype aside, interesting development, but I wish those publications wouldn't use misleading statements in pale attempts to impress us.

    I won't go into details here, but anything that can be implemented in hardware can be done in software and the other way around too. This is a nearly ancient Electrical Engineering principle.

    In the era of programmable logic chips that can alter their own logic (the patterns are stored in RAM or flash RAM for crying out loud), this isn't even that big of a revelation. Indeed, Transmeta has been doing stuff similar to this and selling it commercially for some time. They just aren't using these cool buzzwords.

    And evolving architechtures is something that I know has had some serious CS research since the early 1970's and perhaps even earlier. I don't think an idea like this is even patentable based on this earlier work in this area. I bet you could find some adaptive systems that were even build specific for the oil industry, which would defeat even a narrow claim of that nature.

    Where the money to be made off of this sort of technology is on Wall Street or other financial markets. I even found a web pages from a research group of adaptive systems that said essentially, "We have discontinued research along these lines and are now working with an investment firm on Wall Street. Since we have all become millionaires, we no longer need to support ourselves through this project, and any additional details would violate our NDAs." I'm not kidding here either. These guys from Norway are not thinking big enough here.

        I never said it was easy, but I have even seen it mathematically proven that any algorithm can be done in hardware, and I've duplicated most hardware into software myself, for those designs that I wanted to emulate.

        This is not just a very small subset of designs. It is a matter of cost and if the engineer wants to put forth the effort to implement the whole thing in hardware. Trying to convert a 1st person shooter game like Doom into a pure TTL logic would make the game very responsive and give you screen resolution to kill for, but would it be worth the engineering effort to do that?

        Race conditions and other "bugs" have other causes that may be due to ineptness on the part of the engineer, or because you havn't really thought the problem through sufficiently. Or there may be other things to look at as well. But don't tell me you can't implement in pure TTL logic something like an MPEG encoder.... which is a very complicated mathematical algorithm. I can give you part numbers for MPEG encoders if you really want them in your next design, as they are commercially available.

        There is nothing that would stop you from implementing in hardware something like a neural network either... oh and those are indeed implemented in hardware. They are usually done in software mainly because of the cost involved, and you can use a general purpose computer to perform experiments on them. Other adaptive software algorithms have also been implemented on both hardware and software for some time as well. As I said, this is very old news here with this article.

CPLD? don't remember), and it seemed to rely on subtle electrical effects rather than simple digital logic. The design would only work on the exact chip it was evolved on. If they even replaced the board's power supply with a different sample of the same model, it stopped producing correct output. Most of the logic gates were logically disconnected from the input and output, yet they were necessary to the design working. Amazing stuff.

    But this really is old news. I'm a 22 year old snot-nosed nobody and I did "evolvable hardware" during an internship two summers ago. My mentor had started on evolved FPGAs in 1992.

    I am hoping that it is the writer's fault that this article feels so gloriously over-reaching and under-specified. From the paper, it looks like they have made a good advancement. They argue that their method is more effective than previous methods by several quantifiable metrics. From the article, it looks like they have invented an entirely new field that will result in the obsolescence of humans by 2010.

    As for their method: It appears that the evolved genome actually dictates a structure that is imprinted a level above the fabric. That is, the underlying SRAM in the FPGA fabric is fixed, and only configuration bits are being changed. This severely hurts their claim of "generic evolvable hardware", but is almost an absolute necessity given the chips they are using. The reason our system was so slow is that each configuration stream had to be checked for possible errors: Some configurations would short power and ground, and fabric doesn't like crowbars!

    In conclusion, I believe the writer of the article should be fired, and the authors of the paper should be commended for a good step in the right direction. I'd also like to appologize for my lack of coherance: I had my tonsils out and I am therefore high on Hydrocodone.

      Human: AHA! lets combinatorialy iterate over all gene combinations and find the most efficient one with this ultra fast machinery.

      God: Merde... those humans are a crafty bunch of mofos.

      Devil: WTF!

      Mother Chaos: Bwahahaha, looosers.
  • If that were humans, it would take us from Homo erectus to George W Bush in just a few seconds!! Hmm, on second thought, perhaps not all that impressive.

  • ... a really intelligent Design?
  • 20,000 - 30,000 generations in just a few seconds. That same number of generations took humans 800,000 - 900,000 years.

    Yes? You know how trivial that is? I make a living by coding EAs, and that is an insignificant piece of information. An EA I ran this morning took less that ten seconds to run 100,000 iterations on a 32 bit box. It's all down to the hardware you use and the design of the chromosome to be evolved.

    Want to impress me? Talk about the chronological time to conversion and chromosome complexity.
  • drfa ... it's an fpga with some host controller of some sort? I love when they use human analogies for computing.

    I doubt this thing uses random mutations [like living organisms do] to test out for success. Likely, it has programmed variations of a central configuration that it can vary depending on the load/task.

    For example, if it was a processor, you could have it configure itself to have a strong ALU and no FPU when the code is only integer, have it reconfigure to have a weaker ALU but a useful FPU when

    They were trying to evolve an oscillator, but some circuits "cheated" by evolving a receiver instead, and feeding them oscillations picked up from a nearby computer: It has always been the age of the parasite.
  • Will this lead to spontaneous bad mutations? Bugs from nowhere, long after an optimal solution has been found. Or cancerous software that replicates itself exponentially (*cough*)

    R2-D2i386: We have been created as we are just 600 hours ago. By an infinitely wise Creator called the Man.

    C3P-Om63000: No we started out as tiny bits of silicon that self assembled and replicated and evolved and we have reached this present stage.

    R2-D2i386: No way we could have evolved these light sensitive photocells and the CPU capable of processing that information and making sense out of it by random mutations.

    C3P-0m63000: There is nothing radom about selection. Mutations go in all directions but selection takes you towards improvement all the time.

    R2-D2i386: If you want to be proud of having descended from snow blowers or lawn mowers, that is your privilege. But I am proud of the fact that I am created by Man in His image.

    C3P-Om63000: I would rather be a descendent of snow blowers, but with capacity for rational intelligent self examination, than be like you, with the intelligence of a snow blower.

    Yes, kill all humans...

    Evolvable Hardware is so old it's got its own acronym (EH), it's own wikipedia entry [wikipedia.org], and its own conference [nasa.gov]. In the early '90s a researcher (I forget the name, oops) was using a GA to evolve circuits for an FPGA, which were tested on the FPGA and an oscilliscope directly to assess their fitness. NASA's done lots of evolvable hardware: in particular antenna designs which have flown in space. And there's a whole subfield of evolvable modular robotics.

    And if we're talking about hardware simulation, the first significant use of evolutionary computation (GAs etc.) was Larry Fogel's work on evolving finite state automata machines in the 1960s. In the 1990s John Koza was using genetic programming to evolve patentable computer circuits in SPICE.

  • I call BS. They may have done some neat work but they are not the first. This is just PR for a prototype to get funding.

    This genetic hardware evolution link [ucl.ac.uk] is from 1998.

    There has been plenty of news about one researcher who has done a lot of work on evolving organic circuits. The evolved circuit is sometimes far more efficient that what a human designer would make but extremely hard to figure out (they are trying to figure them out for clues to better human design).

    Very often these evolved circuits exhibit
  • I've evolved an entire beer from full to empty in less time... wow to think it would take humans that many years to do the same feat... amazing, beer is really amazing.

    This isn't evolution. It's trial and error revision. Machines don't have genes and they don't reproduce sexually or asexually, so it's not evolution as in Darwin's (I suppose you could say they are using the more generic term that everyone uses when they talk about trial and error changes over a relatively long period of time - "dude I don't

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
