| Abstract: | A new approach based on genetic algorithms to inverse problem in identification of the steady-state permeability for two-dimensional isotropic medium is introduced.The genetic algorithims is used for solving the inverse problem as an optimization problem.The results of numerical simulation show that the method has a higher accuracy and a quicker convergent speed.And it is easy to program and calculate.It is worth of practical application. |
| Keywords: | tow-dimension isotropic inverse problem genetic algorithms non-linear |
