ADSWITCH: A Simple First-Order Algorithm for Full-Rank Equality Constrained Optimization
Serge Gratton, Philippe L. Toint
A very simple first-order algorithm is proposed for solving nonlinear optimization problems with deterministic nonlinear equality constraints. This algorithm adaptively selects ste…
Recursive Bound-Constrained AdaGrad with Applications to Multilevel and Domain Decomposition Minimization
Serge Gratton, Alena Kopaničáková, Philippe Toint
Two OFFO (Objective-Function Free Optimization) noise tolerant algorithms are presented that handle bound constraints, inexact gradients and use second-order information when avail…
Fast Stochastic Second-Order Adagrad for Nonconvex Bound-Constrained Optimization
S. Bellavia, S. Gratton, B. Morini +1
ADAGB2, a generalization of the Adagrad algorithm for stochastic optimization is introduced, which is also applicable to bound-constrained problems and capable of using second-orde…
A Fast Newton Method Under Local Lipschitz Smoothness
Serge Gratton, Sadok Jerad, Philippe L. Toint
A new, fast second-order method is proposed that achieves the optimal complexity to obtain first-order -stationary points. Crucially,…
prunAdag: an adaptive pruning-aware gradient method
Margherita Porcelli, Giovanni Seraghiti, Philippe L. Toint
A pruning-aware adaptive gradient method is proposed which classifies the variables in two sets before updating them using different strategies. This technique extends the ``releva…
