    And now, Evolutionary Algorithms + POE

    POE is the Perl Object Environment, rather an understatement since it's an event-loop module that allows you to create easily preemptive multitasking programs. Which is why I've used it for POE::Component::Algorithm::Evolutionary, which merges the Algorithm::Evolutionary module with, well, POE. It's not very useful now (and there seems to be something wrong with the documentation), but you can, for instance, run in parallel two evolutionary algorithms side by side.
    The intended evolution of PoCoAE will include an actual evolutionary algorithm, and maybe a distributed computing environment a bit further on. Stay tuned.

    Seems interesting, what are the advantages over other frameworks (like ParadisEO [1], for example)?

    None, actually. ParadisEO is a mature and high performance framework; this is right now in the phase of proof of concept.
    It might be better for people that, like me, favor Perl for programming. BTW, do you know who started and gave the name to EO, the ancestor or ParadisEO?

    Hi, JJ!! :D

    This stuff scares me a lot:

    POE::Component::Algorithm::Evolutionary

    But I am familiar with it, since C++ has the same "::" operator to differentiate between variables and to which class they belong.

    JJ, just a curiosity: Don't you think a little strange using an scripting language to implement a computational resource "consumerist" algorithm?

    It goes even longer; I'm now into POE::Component::Algorithm::Evolutionary::Island::POEtic...
    And to your second question, no, it's not. Even if you consider raw performance, Perl can stand head-to-head to Java in pure EC terms. It might not be so in some case where raw number crunching performance is taken into account, but you could be surprised. In any case, Perl is more straightforward and closer to the actual algorithm than Java, and does not get in the way when creating flexible EA apps.

    It would be wiseful paying attention not to allow your code getting bloated or something like that, JJ. :)

    I am considering what script language I should learn a little better, Perl or Python (or both). What I am looking for has mainly to do with sending terminal commands on UNIX-like machines. I know nothing about those kinds of languages. What would be your advice about that, JJ?

    De: JJ Fecha: 2009-02-18 07:53

    Code is tight, but you have to use meaningful names. Obviously, for terminal commands Perl is probably better.

    Thank You very much, JJ, for your nice advice on scripting languages. :)

    Great job for publishing such a beneficial web site. Your web log isn’t only useful but it is additionally really creative too. There tend to be not many people who can certainly write not so simple posts that artistically. Continue the nice writing sms flood
