This project aims to investigate and advance the field of nonconvex composite optimization, focusing on the recent incorporation of second-order information into iterative models. Two recent sources stand out in this area: Forward-backward envelope for the sum of two nonconvex functions: further properties and nonmonotone line-search algorithms [Themeles 2018] and The Indefinite Proximal …
A class of problems of relatively recent interest and of diverse practical applications, yet difficult to analyze and solve, is the minimization of an lower bounded continuously differentiable function over a disjoint block separable set, involving a penalty and/or constraint that result in the sparsity of such blocks. This project aims to explore this theme from the perspective of the re…
