Wave-equation traveltime tomography by global optimization

Future Work

As we have seen, the global optimization is less accurate than the local fitting. One way to improve the results is to use a hybrid optimization method in which the algorithm either alternates between a global and a local iteration or runs a global search, followed by a local one. In addition, all testing has been done on transmission seismology. The next step is to extend the method to reflection seismology.

Finally, the tests case in this paper are synthetic data. In field data, the noise level is an issue that might degrade the local method even more, in which case the global method can show even more improvement.
