Abstract:

We consider a variable metric line-search based proximal gradient method for the minimization of the sum of a smooth, possibly nonconvex function plus a convex, possibly nonsmooth term. The general convergence result on this method is the stationarity of any limit point of the sequence generated by the method, while convergence of the s...More
