A dynamic objective function technique for generating multiple solution models in seismic tomography

Rawlinson, Nicholas; Sambridge, Malcolm; Saygin, Erdinc


A new technique designed for generating multiple solutions to seismic tomography problems using gradient based inversion is presented. The basic principle is to exploit information gained from previous solutions to help drive the search for new models. This is achieved by adding a feedback or evolution term to the objective function that creates a local maximum at each point in parameter space occupied by the previously computed models. The advantage of this approach is that it only needs to...[Show more]
