f A High-Order Pertubative Approach - Examples of Inversion

A common procedure in nonlinear seismic inversion involves least squares optimization (LSO) [6,8] implemented by various Newton type iteratie algorithms [4]. Recent papers [2,3] indicate that the highorder perturbations can overcome the problems of the LSO concerning initial guess, a priori information, CPU/acquisition costs, etc. The purpose of this paper is to show how such additional constraints can be incorporated into the available LSO algorithms without their special modification.
