In Chapter 2, a nonmonotone trust region method with a line search technique is presented. Unlike traditional trust region methods, our method does not restrict a monotonic decrease of the objective function value at each iteration, but only requires an average of the successive objective function values decreasing.

第二章，我们提出了一类带线搜索的非单调信赖域算法，与传统的信赖域方法不同的是：我们的算法不要求目标函数值在每一步都有充分下降，而是要求目标函数的连续平均值充分下降。

Compared with traditional discrimination method, this method is one that utilizes less iteration steps to find the optimum solution of the linear programming problem.

为寻找最优解，就需要求出基础可行解，并判断是否为最优解。单纯形法是求解线性规划问题的强有力的工具。通常采用

When it is used to solve contact problems,multiplepairs of contact points can be updated in each iteration,other thansome methods such as Thail-Van de Panne method and Goldfarb-Idnani method,which update only one pair of contact points at eachiteration.

用拟有效集方法解接触问题，每次迭代可以更换一组接触点对而不是某些方法只能更换一个接触点对，因此大大提高了解接触问题的效率。

By studying the spectrum properties of coefficient matrix and the regular parameters at the iterative procedure of the first class regular method , we assign a uniform parameter for the inner iteration . Simulation results show that this method for choosing regular parameter is correct and the outer iterate convergence for high contrast object.

这两种方法的正则化效果取决于迭代的次数，我们通过对静态正则化方法中逆散射方程系数矩阵的谱特性、正则化参数等进行分析，对这类迭代正则化方法选取了统一的正则化参数，使得外部迭代方法收敛。
