Since the homogeneous model can approximate the objective function better than the quadratic model, the new algorithm is superior to the classical trust region algorithm.
由于该模型比二次模型更近似目标函数，故新算法优于传统的信赖域算法。
This paper presents a trust region algorithm based upon the homogeneous model. The traditional trust region algorithm based on the quadratic model is one of its special cases.
提出一种基于齐次模型的信赖域算法，传统的基于二次模型的信赖域算法只是它的一个特例。
The range correction efficiency can be enhanced obviously with strap-down SINS adopted, and the precision of the method for the quadratic model is higher than that for the linear model.
