查询词典 dual problem

To solve the problem, the method that all the elements of the image of dual absolute quadric are transformed into the same magnitude is proposed.

To overcome the shortcomings of existing algorithms, the distributed parallel reactive power optimization algorithm based on sub-area division of the power systems is proposed according to the distributed and decentralized characteristics of the power system. Here, multi-objective function and soft constraints are modeled using fuzzy sets, and the multi-objective reactive power optimization problem is solved by the direct nonlinear primal-dual interior point algorithm.

针对目前无功电压优化算法存在的不足，根据电力系统分布、分散的特点，提出了基于电网分区的分布式并行无功优化算法，并对其进行了多目标、软约束的模糊化处理和离散控制变量的罚函数处理，利用直接非线性原—对偶内点法寻优求解。

The problem of allocation Of financial resource between urban and rural area reflects the urban-rural dual structure.

我国金融资源的城乡配置问题是城乡二元结构在金融领域的突出反映。

Based on the asymptotic homogenization theory, the periodic boundary conditions for the unit cell were established by using the ANSYS parametric design language. The problem of the unit cell was solved by finite element method and the effective elasto-plastic properties of dual phase steels were obtained.

在渐近均匀化方法基础上，假设双相钢的结构为周期排列，通过ANSYS参数设计语言建立周期性边界条件，用ANSYS有限元程序对3种平面应变模型的单胞进行求解，得到双相钢的有效弹塑性性能，并与其他计算结果进行比较。

这些都是比较有利的位置，我们可以安装双插槽的显卡，在制度sli没有问题。

A boundary identification problem of two-dimensional unsteady heat conduction was solved by using dual reciprocity boundary element method and conjugate gradient method-based inverse algorithm.

采用基于双倒易边界元法和共轭梯度法的反演算法求解二维非稳态导热边界识别问题。

It transforms the primal problem into an ordinary optimization problem with an explicit dual function and simple constraints, with smaller size than primal constraints. It is convenient for engineering application.

该方法不仅给出了原问题显式形式的对偶函数，而且对偶变量的数目仅等于原问题部分约束的个数，原来的线性0-1规划问题被转化为只有简单约束的普通优化问题，极大地方便了工程应用。

The incomparability comes from two sources: the first is the problem of statistic system. The income data in China are distinct surveys, using different questionnaires and administered by different units within National Bureau of Statistics. The second is the problem of China's economic structure. China's current dual economic structure determines the disparity between rural and urban residents.

所谓"不可比性"主要包括两层含义；首先是统计数据本身的问题，国家统计机关公布的居民收入分配数据分为"城镇居民"和"乡村居民"两部分，在统计口径、数据结构和公布形式上都存在差异；其次是城乡二元结构体制的存在所决定的不可比性，即中国目前的城乡二元结构体制造成了城、乡居民经济生活形态的差异，同等"收入"为城、乡居民带来的购买能力、生活质量和财富水平并不相等。

By this comparition,the advantage which use double structure encode to solve knapsack problem is proved. Genetic Algorithm ; Knapsack problem ; dual-structure encode

解决背包问题的关键在于约束条件的处理，目前一般采用惩罚函数的方式处理约束条件，这种方法当问题规模较大时，尽管可行，但搜索效率很低，甚至有时得到的结果比一般的启发式算法还
