Well, as often occurs with evolutionary learning apps, there is artistry in creating the fitness function...
This is something we (try to) deal with in NM/OpenCog via using probabilistic inference to automatically come up with fitness functions for evolutionary procedure learning But the Euphoria guys seems to be doing a lot of manual fitness function tuning ben On Thu, May 1, 2008 at 5:49 PM, Mike Tintner <[EMAIL PROTECTED]> wrote: > The link from Lukas seems to suggest that applying this technology is > something of an art (is that right?): > > "As a side note, the fickle nature of the evolutionary approach is the > primary reason why euphoria isn't middleware; the team at NaturalMotion > helps you integrate it.
