    I love this part:

    Perhaps the most cunning use of an evolutionary algorithm, though, is by Dr Koza himself. His team at Stanford developed a Wi-Fi antenna for a client who did not want to pay a patent-licence fee to Cisco Systems. The team fed the algorithm as much data as they could from the Cisco patent and told the software to design around it. It succeeded in doing so. The result is a design that does not infringe Cisco's patent--and is more efficient to boot. A century and a half after Darwin suggested natural selection as the mechanism of evolution, engineers have proved him right once again.


    But who's to stop the person who wrote the algorithm to patent the solution that bypassed the original patent? Or the algorithm itself for that matter?

    Patents were supposed to encourage innovation, but modern patent law has evolved in a way that makes it more of a hindrance than a help. You basically have to have a large corporation and a battery of lawyers behind you to support your patent application, and the corporations aren't even interested unless they are very sure they can see a path to big profits. For the corporations the big attraction is that the patent grants them monopoly profits, and they could not care less about the social values (or harms) of the innovations themselves. From that purely monetary perspective it makes perfect sense to focus on the value of patents for blocking competitors and for lawsuits--though SCO showed that the strategy doesn't always work.

    I think the fundamental problem is that the values of patents are too highly variable, and this variability has completely overwhelmed the simple-minded idea of a temporary monopoly. There are cases where it makes sense to motivate innovation by the exclusive monopoly, but almost never for the specific period of time that is hard-coded into patent law. Some patents should lapse more quickly, though of course the companies will argue they should last *MUCH* longer, and they have a lot of lobbying money to push with. Some patentable ideas are very quick and inexpensive to develop, while others take years and lots of money, but patent law doesn't really consider such trivia.

    The bottom line dynamic is that most innovation has to start within an individual, but patents have become a team sport. If you aren't on the right team, it doesn't really matter how innovative your ideas are. You're very unlikely to succeed at the patent game without such a team.

The only difference between this and "natural" evolution is the environment (and possibly procreation methods) was created by us, rather than just existing for whatever reason the rest of the universe does. And if we get something that survives in an environment of "receive these WiFi signals or you die", well that's useful.

    Two problems:

    1. For the past 10+ years I keep seeing various articles talking about evolution design and they are all about antennas and simple analogue circuit designs. Antennas are certainly susceptible to evolutionary design, but if we'll be driving the industry forward we'll need to throw lots of R&D to develop evolutionary design algos that can design something more complex. My point is, it's hugely promising, but it's still not here in a big way.

    2. The bigger problem, and which is what caused my exclamation in the title: there's no way to avoid overly broad patents. Evolutionary designs in fact often arrive at designs that match exactly various patents. Which means, when your super computer arrives at a working design, you still need to go through all the tedious work of verifying it's not patented, and if it is, start the algo again and hope for the best.

    And the limit for rerunning the algo plenty of times to get patent-free design is the same such as manual design: we don't have infinite time, and the solutions to a problem are sometimes finite, and not that many.

    I think patents should be left in place, but their running period should be shortened. The industry is developing at such an amazing pace that we make more progress in an year, than what took 10 years before.

    • You act as if this is a bad thing. Evolution works on the scale of societies as well. If one society becomes unfriendly to innovation, it will be marginalized as it loses technical dominance. Ultimately the most powerful societies will be the ones that are friendly to innovation because the others couldn't keep up. So it works out nicely.
      • Excuse me, but it IS a bad thing, from your point of view, if idiots withing your own society are CAUSING it to "devolve" and be anti-competitive.

        • From an individual perspective, yes, especially if you're rooted to one society (otherwise just move wherever the innovation is going). But in terms of total innovation by humanity, it isn't a major issue.

          If societies tend to become complacent and pass anti-innovative policy such as this once they've achieved power, all the better; it lets other societies advance (relatively speaking), which encourages competition, which spurs innovation like nothing else.

          Thus, I'm not happy about this as an individual,

  • Genetic algorithms are the Ruby on Rails of optimization problems. If you can define a state space and a fitness function, you're almost certainly better off using (non-)linear programming, constraint programming, or a local search method like tabu search.

    To quote the AI Bible (AIMA 2e, Russell and Norvig): [It] is not clear whether the appeal of genetic algorithms arises from their performance or from their aesthetically pleasing origins in the theory of evolution.

    But because GAs are so intuitive for anyon

    • If you can define a state space and a fitness function, you're almost certainly better off using (non-)linear programming, constraint programming, or a local search method like tabu search.

      Linear programming and hill-climbing algorithms have their place when it comes to simple search spaces, however when you have many dimensions and a vast non-linear search space none of the algorithms you named will get very far.

      In the past I had similar discussions with a prof on search spaces with dozens of dimensions. H

  • It could well be, that the University's research costed more, than whatever the patents-holder(s) would've charged for the licensing...

  • What would happen if open source organizations, such as the FSF, looked at a technology, predicted where it was going, and then came up with the most probable solutions, and patented them?

    And then offered indemnity only to those companies which published their source under an open source license?

    I hear a lot of whining and moaning about bad patents, but not a lot of people are willing to invest the mere $600 it takes to file a patent application. When you think about it, if even 1/10th of the open s

    • Yet, for all of the collective intelligence of the geek community, we'd rather sit on our collective asses and whine, rather than actually do something about the abuses of patent law.

      That's because this is a market economy, and no one wants to do uncompensated labor.

  • Is probably one of the best ideas I've heard in a while. It defeats patents, and makes our stuff better. Down with the system!

  • While it is true that evolutionary algorithms can be used to do an end-run around patents, it can also be used for new patents. In my opinion, this is what Genetic Programming, Inc. hopes to do: generate patents through evolutionary algorithms. (See, here [genetic-programming.com], for example, on genetically derived patents -- in section 2). Dr. John Koza, as far as I know, teaches at Stanford and also runs this company, and he is considered the father of genetic programming. He has patents on genetic programming [genetic-programming.com] as well.
