Adaptive Regularization Algorithms with Inexact Evaluations for Nonconvex Optimization
S. Bellavia, G. Gurioli, B. Morini +1
A regularization algorithm using inexact function values and inexact derivatives is proposed and its evaluation complexity analyzed. This algorithm is applicable to unconstrained p…
Adaptive Cubic Regularization Methods with Dynamic Inexact Hessian Information and Applications to Finite-Sum Minimization
Stefania Bellavia, Gianmarco Gurioli, Benedetta Morini
We consider the Adaptive Regularization with Cubics approach for solving nonconvex optimization problems and propose a new variant based on inexact Hessian information chosen dynam…
Spectrally Accurate Energy-preserving Methods for the Numerical Solution of the "Good" Boussinesq Equation
Luigi Brugnano, Gianmarco Gurioli, Chengjian Zhang
In this paper we study the geometric solution of the so called "good" Boussinesq equation. This goal is achieved by using a convenient space semi-discretization, able to preserve t…
