On the Evaluation Complexity of Composite Function Minimization with Applications to Nonconvex Nonlinear Programming.
We estimate the worst-case complexity of minimizing an unconstrained, nonconvex composite objective with a structured nonsmooth term by means of some first-order methods. We find that it is unaffected by the nonsmoothness of the objective in that a first-order trust-region or quadratic regularizatio...
