Encoding system of genetic algorithm determines the searching abilities of genic operations.This paper present a Hybrid Encoding Genetic Algorithm (HEGA),which is based on two encoding mechanism.In the procedure the higher mutating probability should be taken in order to create more chances for the production of new genes.After analyzing the genetic operations and their encoding procedures,it is easy to find out it is effective method to mix the two encoding into the algorithm and it may be helpful to solve the inversion of geophysical data.The paper introduces the theoretical computation of synthetic models and the application of gravity inversion of 2D model by using HEGA.
