I assume you're being sarcastic; they do point out in the intro and at the end that a deep RL agent could be trained to do the topology selections, but that would be more work to get going than some simple evolutionary operators, and is left to future work. Don't worry, I'm sure it'll be A3C all the way down eventually...
