A simple Newton method for local nonsmooth optimization
Adrian Lewis, Calvin Wylie
Superlinear convergence has been an elusive goal for black-box nonsmooth optimization. Even in the convex case, the subgradient method is very slow, and while some cutting plane al…

Active-set Newton methods and partial smoothness
Adrian S. Lewis, Calvin Wylie
Diverse optimization algorithms correctly identify, in finite time, intrinsic constraints that must be active at optimality. Analogous behavior extends beyond optimization to syste…
