摘要
给出了利用模拟退火算法求解热传导方程稳恒源项识别的一种新方法.该方法把源项识别反问题转化为优化问题,用模拟退火算法求解.通过数值模拟对本算法的可行性和有效性进行了验证,结果表明,此法是可行的、有效的,并且具有较高的精度.
In this paper, a new approach, which is based on simulated annealing algorithm for source term identification of heat conduction equation, is presented. It transforms the source identification problem into the solution of an optimization problem using simulated annealing algorithm. The practicability and the availability of the method were verified by digital simulation. The results have showed that the method was practicable with relative high precision.
