I don't know enough about evolution so this could be way off, but I'd guess the idea is that nature "designs" the algorithm via evolution (imagine some Turing machine's code/neural net equivalent being slowly improved by trial and error over hundreds of millions of years) where the result appears like minimising a global cost/action-value function of the species and maximising its probability of survival. The question if this is different in principle from nature "implementing" a supernova or "implementing" electromagnetism or "implementing" a planet is an interesting one, but it seems like in both cases once it starts (cosmic evolution or life evolution) mathematics can be used as a map of the territory.
