Abstract

Summary

Function Optimization requires a set of parameters to solve numerical problems. In this paper Very Fast Simulated Annealing (VFSA), a novel extension of Simulated Annealing method has been insinuated to perform AVO Inversion with a constraint from travel time inversion of seismic reflection data. The Inversion has been performed for noise free as well as 2% noisy synthetic data, and the estimated results are closer to the elastic parameters (Vp, Vs and density) of the true model. The sensitivity analysis depicts robustness of the method and the results do not alter considerably by the addition of random noise.
