Scalable subspace methods for derivative-free nonlinear least-squares optimization [PDF]

open access: yesMathematical programming, 2021
We introduce a general framework for large-scale model-based derivative-free optimization based on iterative minimization within random subspaces. We present a probabilistic worst-case complexity analysis for our method, where in particular we prove high-

On the adaptive selection of the parameter in stabilized finite element approximations [PDF]

open access: yes, 2013
A systematic approach is developed for the selection of the stabilization parameter for stabilized finite element approximation of the Stokes problem, whereby the parameter is chosen to minimize a computable upper bound for the error in the approximation.

Extended Seventh Order Derivative Free Family of Methods for Solving Nonlinear Equations

open access: yesMathematics, 2023
A plethora of applications from Computational Sciences can be identified for a system of nonlinear equations in an abstract space. These equations are mostly solved with an iterative method because an analytical method does not exist for such problems ...
