AI criteria for setting colony type

[Jubala]

I have noticed that the AI is sometimes extremely stupid in choosing what type of colony a new colony should be. I have seen huge undomed AI planets with mineral contrations of 149% being used as farming colonies when the organics concentration on that planet was 13%. Talk about a waste of resources! I checked what the AI colonies in a couple of my old savegames was doing and to my horror I discover this more the rule than the exception. So I went over the settings file for choosing colony types and to me it seems the AI's only criteria for how to use a planet is some abstract value on how many planets of type x are allowed in one system or in the empire and so on. It seems to me the concentrations of resources on the planet has no bearing whatsoever on the AI's decision in how to use it. Which means the AI ends up with alot of planets being used for something they are clearly unsuited for. Like my example above. IMO the most important criteria for choosing how to use a planet is it's concentration values. And as has been mentioned elsewhere the AI doesn't reevaluate planets or scrap facilities to build computers or robotoid factories.

If there was an option at startup to set all planets to a uniform concentration value (100%) this wouldn't be so big a problem. However, such a game would be rather boring. Alot of variety would dissapear.
