2008/9/8 Benjamin Johnston [EMAIL PROTECTED]: Does this issue actually crop up in GA-based AGI work? If so, how did you get around it? If not, would you have any comments about what makes AGI special so that this doesn't happen? Does it also happen in humans? I'd say yes, therefore it might

Hi, I am curious about the result you mention. You say that the genetic algorithm stopped search very quickly. Why? It sounds like they want to search to go longer, but can't they just tell it to go longer if they want it to? And to reduce convergence, can't they just increase the level of

You can implement a new workaround to bootstrap your organisms past each local maximum, like catalyzing the transition from water to land over and over. I find this leads to cheats that narrow the search in unpredictable ways, though. This problem comes up again and again. Maybe some kind of

Hi, I have a general question for those (such as Novamente) working on AGI systems that use genetic algorithms as part of their search strategy. A GA researcher recently explained to me some of his experiments in embedding prior knowledge into systems. For example, when attempting to

I'd just keep a long list of high scorers for regression and occasionally reset the high score to zero. You can add random specimens to the population as well... On 9/7/08, Benjamin Johnston [EMAIL PROTECTED] wrote: Hi, I have a general question for those (such as Novamente) working on AGI
