摘要
本文研究了一种抛物型方程间断参数的识别问题.利用未知间断点作为反演点和遗传算法优化参数,获得了间断点和反演解.数值实验结果表明反演解和真实解非常接近.
In this article, we study the discontinue parameter identification of partial differential equation problem. Based on discontinue point which is regarded as inverse point, we employ genetic algorithm to optimize parameter of inverse problem and obtain discontinue point and inverse solutions. The numerical results demonstrated that inverse solutions approximate true solutions.
