An Inexact Minimization Trust-Region Algorithm: Globalization of Newton's Method
In this work we define a trust region algorithm for approximating zeros of the overdetermined nonlinear system F(x) = 0, where F: R^n -> R^m is continuously differentiable. Instead of the l2 norm, arbitrary norms can be ...
Comparing Objective Functions for Velocity Inversion
The success of automatic velocity inversion is highly dependent on the numerical tractability of the optimization problem which defines the solution. The purpose of this paper is to compare the objective (cost) functions ...
