A thing that is also not novel. People have done search for optimisations for at least the past decade.

Sure, but the whole point is to reduce this kind of search to RL, which is a very general framework. Their paper shows that such a generic approach can solve a very specific problem, and solve it well. But, their paper is about improving RL, not about improving sorting.

sometimes one has to wonder how RL can be both so generic and still be qualification to publich in nature again and again and again ;)
