RL seems great for things like training video game agents and have seen videos of this, but fail to understand where RL can be applied in the real world.&lt;p&gt;It reminds me a bit of genetic algorithms.  GA is the &amp;#x27;last resort&amp;#x27; when you truly know nothing about how to model your problem.&lt;p&gt;What is the sweet spot for RL?</text></comment>
