You'd be hard pressed to find anything more comprehensive than the wiki. Have you looked at the tutorials yet?
But really it won't make sense until you try to write a bot and debug it.
It's not really a lack of information - clearly a lot of work has been put in - it's just a bit tricky to figure out what to do in what order to learn. Obviously, its an encyclopedia, not a tutorial. The bot tutorials are very helpful, and what I'm trying to go through. But I'm not totally sure what the next step should be.
Maybe I should outline what I'm thinking and get advice. The two ideas that have popped into my head watching sims are:
1. I'd like to do some experiments with sustainability. Using default levels of photosynthesis, develop a way for a population of very basic veggies and single bots to start with random values and through mutation reach a sustainable level of consumption as quickly as possible.
2. Just try and get meaningful evolution as quickly as possible.
That's not terribly specific, but they're the projects I'd like to work on. Any thoughts?
