查询词典 problem

OD estimation was divided into fixed steps, with every step containing a bi-level programming. The upper-level problem was a generalized least squares estimator, while the lower level problem was a stochastic user equilibrium model. Namely, based on generalized least squares estimator and stochastic user equilibrium, a new estimator of the OD matrix was proposed by target matrix and traffic counts updating.

将OD估计分为固定的步数，每一步都是一个双层规划，上层为广义最小二乘估计，下层为随机用户均衡分配模型，即以广义最小二乘估计和随机用户均衡分配模型为基础，通过更新估计模型中目标矩阵和实测路段上的流量来估计OD矩阵。

It is not only a economic and social problem but also a legal problem.

这不仅是一个经济和社会问题，也是一个法律问题。

All was unexpected. Likin, though, was temporary tax that the Qing Dynasty established for raising money to repress the taiping rebellion. It had been censured for seventy eight years. This showed that the existence of likin had its profound background of economy and society. Abolishing likin was to "change a little, then influence the whole", and it existed contradiction not only between China and other countries, but also between the center and the local authority. The problem of likin systems abolition was the problem about not only economy but also politics.

厘金虽然一开始是清王朝为筹措镇压太平天国运动军费而设立的临时税种，但其屡遭非议却长达78年的历史表明，厘金的存在有其深刻的经济与社会背景，"裁厘"可谓是"牵一发而动全身"，不仅存在着中国与各国列强之间的矛盾，而且存在着中央与地方政权之间的矛盾，厘金的裁撤问题，既是经济问题，又是政治问题。

For the linear problem, the linearity of the problem is also well preserved in the merit functions. The global convergence, local superlinear or quadratic convergence and finite convergence for linear problems of the proposed algorithms are also obtained under conditions as above or even weaker.

基此构造的互补和混合互补问题的算法，均具备在前述条件或比其更弱条件下的全局收敛性、局部超线性或二次收敛率以及在线性情形下的有限步收敛性。

For the original infinite dimensional problem, if the inexact quasi-newton method with Broyden updating can not converge quickly , for example, it can not attain super linear convergence rate , then when the discretization is becoming finer and finer , we can not get fast convergence rate for the corresponding finite dimensional problem.

对于原来的无限维问题，如果使用不精确Broyden方法不能得到较快的收敛速度，比如超线性收敛性，那么当离散化逐渐加细的时候，对于所得的有限维问题使用不精确Broyden方法也不可能得到较快的收敛速度，所以有必要在无穷维空间上对收敛性问题加以分析，从而为不精确拟牛顿法结合投影法求解算子方程做好准备。
