摘要

Inverse problem in geophysics is usually described as data misfit minimization, which has difficulties such as multi-parameters, nonlinearity and ill-posedness. Local optimization based on function gradient can not guarantee to find out globally optimal solutions, unless a starting point is sufficiently close to the solution. Some global optimization methods based on stochastic searching mechanism converge in the limit to a globally optimal solution with probability 1.
