The universe doesn't optimize entropy, it is people who make strong inferences coming out this way. See e.g. E. T. Jaynes (1988). `The Evolution of Carnot's Principle'. Maximum-Entropy and Bayesian Methods in Science and Engineering 1:267+ (PDF)

On the other hand, you can always look at how something is, and formulate an optimization problem for which the way things are is a solution, saying that "so, the system optimizes this property". This is called variational method, and it isn't terribly ontologically enlightening.
