A variational method for unconstrained optimization problems

Pages 491-503 | Received 15 Feb 2006, Accepted 21 Dec 2006, Published online: 21 May 2007
 

Abstract

We introduce a new method for solving an unconstrained optimization problem. The method is based on the solution of a variational inequality problem and may be considered a modified trust region algorithm. We prove the convergence of the method and present some numerical results.
