A simple and practical adaptive trust-region method
Fadi Hamad, Oliver Hinder
We present an adaptive trust-region method for unconstrained optimization that allows inexact solutions to the trust-region subproblems. Our method is a simple variant of the class…

A consistently adaptive trust-region method
Fadi Hamad, Oliver Hinder
Adaptive trust-region methods attempt to maintain strong convergence guarantees without depending on conservative estimates of problem properties such as Lipschitz constants. Howev…

The Price of Adaptivity in Stochastic Convex Optimization
Yair Carmon, Oliver Hinder
We prove impossibility results for adaptivity in non-smooth stochastic convex optimization. Given a set of problem parameters we wish to adapt to, we define a "price of adaptivity"…
