چکیده
In this paper we presented a novel method for inversion of geophysical data while the regularization term is implied in a meta-heuristic algorithm. Due to the integration of the regularization term in the body of the stochastic algorithm, some of the main challenges such as defining a weighting matrix and finding the suitable regularization factor are resolved. This paper elaborates some of the main ideas of indirect regularization of geophysical data for genetic algorithm and uses a noisy synthetic model to validate the stability and efficiency of these techniques. All computations have been done in the GNU octave 5.1.0 environment.

Abstract
In this paper we presented a novel method for inversion of geophysical data while the regularization term is implied in a meta-heuristic algorithm. Due to the integration of the regularization term in the body of the stochastic algorithm, some of the main challenges such as defining a weighting matrix and finding the suitable regularization factor are resolved. This paper elaborates some of the main ideas of indirect regularization of geophysical data for genetic algorithm and uses a noisy synthetic model to validate the stability and efficiency of these techniques. All computations have been done in the GNU octave 5.1.0 environment.
