In games, AI is not my area. But, what I've seen is that games try to avoid training-based AI because it is difficult to get predictable, controllable results.

In games, AI is not my area. But, what I've seen is that games try to avoid training-based AI because it is difficult to get predictable, controllable results. Training an neural/genetic/whatever system is great until a designer asks you to code in a few exceptional situations and a few extra guarantees. However, there is apparently some movement into that area going on. Here's a recent vid about game AI. https://www.youtube.com/watch?v=jse_ZleruJU&t=11m44s https://www.youtube.com/watch?v=jse_ZleruJU&t=11m44s It talks about the progression from FSMs, to Behavior Trees, to Utility AI, into Neural Nets and eventually Neural Evolution.
