Algorithms for Decision Making

Control theory is indeed, quite cool, and under-discussed in most circles.

Also, unfortunately, classical control theory is primarily good for linear time-invariant dynamics in the frequency space of the Laplace transform. If you can't locally linearize your model and/or need to learn a model, classical control approaches are underdeveloped, and everyone has switched to optimal control and RL.

I think you might mean something different by optimal control than I would. I'd bucket that into control theory, but it seems you're drawing a distinction.

I would distinguish between classical control and optimal control. In the former, you don't have a (Hamilton-Jacobi-)Bellman equation to solve, while in the latter, the approximate dynamic programming is The Hard Part.
