Optimization Methods in Geophysics

Geophysical parameter estimation is essential for solving the inverse problem. The large number of parameters of subsurface models make optimization methods attractive. This session addresses the use of gradient schemes, linear and non-linear programming, expert systems, simulated annealing, and genetic algorithms. The applications include signal processing, deconvolution, statics corrections, velocity analysis, and other aspects of geophysical inverse theory.
