Comparison between Two Kinds of Optimize Algorithms Application in the Inversion Fault Slip Velocity

The Monte Carlo and recently the ant colony algorithm which proposed for solving hard combinational optimization problems are introduced, And in view of the fault parameters characteristics, combined dislocation of the theoretical model simulated ground fault displacement field data on inversing the three-dimensional slip velocity with two kind of optimized methods, Compared the two optimization inversion results, The results show that ant colony algorithm is superior to Monte Carlo method in reliability and stability.
