摘要: 本文讨论了如何由边界数据对一个位势系统的界面进行估计的技术,它可以化为一个泛函的约束极小化问题,解法采用了增广Lagrange乘子法,数值计算采用了有限元离散化技术。

Abstract: An estimation technique about the interface of potential systems from the boundary data, which can be transformed into a constrained minimization problem of functionals, is discussed. The well-known augmented Lagrangian algorithm applies to solutions in the numerical calculations with finite element discretization technique.

Key words: parameter estimation, inverse problems, augmented Lagrangian algorithms
