On the Evaluation Complexity of Composite Function Minimization with Applications to Nonconvex Nonlinear Programming.

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...
