Logarithmic Mating

Last night I made an subtle change to the genetic algorithm used by Electric Sheep: reproduction is now proportional to the log of the rating, rather than to the rating. Previously each vote for a sheep was essentially a lottery ticket for reproduction. When the server had space for a new sheep, it picked the parents by lottery. This seemed fair to me, but the ratings also control the life-span of the sheep. The result was total number of children had by a sheep was proportional to the square of its rating. Hence reproduction was dominated by the top players. The log factor should correct this.

This makes me wonder what the optimal genetic algorithm is, and what practical experiment could compare two algorithms? How can we not waste any of the information of the votes and the energy of the rendering of the sheep? Posted by spot at June 24, 2005 02:05 PM

I'm planing to try to "answer" your question but I think there's no clear response a genetic algoritm is a sum of choices do by an humain. I'll try to explain me further last week in a message for you last week only because I'm french and a week-end is not to much to translate my bad french into english =:) I'm very interrested in genetics algoritms and sheeps Posted by: renard at June 30, 2005 08:11 AM
