摘要
给出了利用遗传算法求解二维恒定各项同性介质渗透系数反演的一种新方法,该方法把参数反演问题转化为优化问题通过遗传算法求解.数值模拟结果表明:该方法具有精度高、收敛速度快、编程简单、易于计算机实现等优点,值得在实际工作采用.
A new approatch based on genetic algorithms to inverse problem in identification of the steady-state permeability for two-dimenslonal isotropic medium is introduced. The genetic algorithims is used for solving the inverse problem as an optimization problem. The results of numerical simulation show tlaat 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.
