Trust region method example
WebHence, SpaGrOW should also be applicable in domains that are further away from the minimum. This can only be realized efficiently by a local consideration. The minimization of SpaGrOW is performed in a small compact trust region. As the minimum can be situated at the boundary of the trust region, the method becomes an iterative procedure. Webscribe FWI based on the trust region method. In order to solve the subproblem in the trust region algorithm, the two dimensional subspace method is describe d. 2.1. Forward Method The source-free time-domain two dimensional (2D) elastic wave equations can be written as [19] 2 2 2, u u v u uv t x xy x y y x ρ λ µµ
