Query: On the Application of Danskin's Theorem to Derivative-Free Minimax
  Optimization   Motivated by Danskin's theorem, gradient-based methods have been applied with
empirical success to solve minimax problems that involve non-convex outer
minimization and non-concave inner maximization. On the other hand, recent work
has demonstrated that Evolution Strategies (ES) algorithms are stochastic
gradient approximators that seek robust solutions. In this paper, we address
black-box (gradient-free) minimax problems that have long been tackled in a
coevolutionary setup. To this end and guaranteed by Danskin's theorem, we
employ ES as a stochastic estimator for the descent direction. The proposed
approach is validated on a collection of black-box minimax problems. Based on
our experiments, our method's performance is comparable with its coevolutionary
counterparts and favorable for high-dimensional problems. Its efficacy is
demonstrated on a real-world application.
