Minimization over the l1-ball using an active-set non-monotone projected gradient
Andrea Cristofari, Marianna De Santis, Stefano Lucidi +1
The l1-ball is a nicely structured feasible set that is widely used in many fields (e.g., machine learning, statistics and signal analysis) to enforce some sparsity in the model so…
An augmented Lagrangian method exploiting an active-set strategy and second-order information
Andrea Cristofari, Gianni Di Pillo, Giampaolo Liuzzi +1
In this paper, we consider nonlinear optimization problems with nonlinear equality constraints and bound constraints on the variables. For the solution of such problems, many augme…
Active-set identification with complexity guarantees of an almost cyclic 2-coordinate descent method with Armijo line search
Andrea Cristofari
In this paper, it is established finite active-set identification of an almost cyclic 2-coordinate descent method for problems with one linear coupling constraint and simple bounds…
