About 20 years ago, I experimented by adding simple neural net and genetic algorithm based agents to quake2. Here’s what I did back then: Ecosystem: Constructing a simple self-perpetuating society of adaptable agents (archived) I was thinking about that again today. It might be fun to develop a suite of mini experiments using genetic learning an neural net learning in little q2 agents. To setup little ecosystems on server processes and let them run for days and weeks and see what happens.
