带不等式约束的间接平差模型的三种解算方法比较

摘要

讨论附加不等式约束的间接平差模型的三种经典算法:Lemke法、势函数法以及迭代乘子法,这三种算法都是基于K-T条件的,算法的构造也是以得到K-T点为目标.用同一组数据,采用三种算法,得到了一些有用结论.%Three classical algorithms for parameter adjustment: Lemke' s method, potential function method and iterative multiplier method,based on K-T conditions are discussed, and some useful conclusions from the results of the case study which applied the three algorithms are given.
