文摘:该文针对不同类型观测值的非线性最小二乘平差，介绍一种将问题分离后再解算的基于变尺度法的解析方法。
To the inequality constrained least squares adjustment problem , this paper converts many inequality constraints into one equality constraint by using aggregate function of non - linear programming ; a basic augmented lagrangean algorithm can obtain the solutions for equality constrained non - linear programming problem and the solutions are identical to those obtained by the bayesian method and / or simplex algorithm
摘要对不等式约束最小二乘平差问题，借助非线性规划中的凝聚约束方法把多个不等式约束转化为一个等式约束，采用拉格朗日极值法求解，解与贝叶斯解或单纯形解一致。
