查询词典 explicit function

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。

Using the dynamic programming approach, an explicit solution to the value function of the optimal portfolio problem is obtained by the HJB equation, and the optimal investment strategy is given.

在风险投资服从Heston模型的假设下，研究了幂效用函数的最优投资组合问题，利用动态规划方法通过HJB方程得到最优投资组合价值函数的显式解，并给出最优投资策略。

Since all javascript syntax functions derive themselves from the base-class function, it is unnecessary to provide an explicit reference to the self-object: from anywhere within an ECMA-style script, you can obtain a reference to the self-object through the keyword "this", which is the same as the "me" keyword, but with minor differences.

因为所有的javascript语法中函数都是从基础类函数派生而来，它们不必显示的声明指向自己的对象：在ECMA风格脚本的任何地方，你都可以通过关键字"this"获得指向当前对象自己的引用，就象关键字"me"的功能一样，只是稍有不同。

Applying these results to the topography, we deduce the explicit expression of the error propagation formula with regard to the non-linear function.

In this paper,taking advantage of some properties of Gamma function,we get the explicit solution. Some simulation results are also given in this paper. In chapter three, we discuss the problem under censored data in three circumstances.

一直以来，对Weibull分布参数的矩估计都是采用数值方法求解，本文利用Gamma函数的一些性质，得到了估计的显式解，并从理论和数值模拟说明此种方法相比其它方法的优越性。

It has both explicit and implicit features with its function realized more in the latter.

它既具有显性课程属性，也具有隐性课程属性，但更多地在隐性课程范畴中发挥其课程功能。

By using the techniques of an explicit criterion to determine the number of real roots of a univariate polynomial in ( [13] , [73] ); B-net form of bivariate splines function; discriminant sequence of polynomial (cf. [13] , [73] ) and the number of sign changes in the sequence of coefficients of the highest degree terms of sturm sequence, this paper determines the number of real intersection points two piecewise algebraic curves whose common points are finite.

3：利用杨路，张景中，侯晓荣在文献（[13]，[73]）中关于一元多项式实根的显式判准，以及二元样条函数的B-网形式，多项式的判别序列和Sturm序列的最高次数项系数序列的变号数，本文给出了两个分片代数曲线的实交点数的计算公式。

However, asymmetric Laplace distribution has only 2 parameters and explicit distribution function form, it can fit the data of stock returns well. Consequently it greatly facilitates the calculation of optimal portfolios and the management of financial risk.

非对称拉普拉斯分布有明确的解析表达分布函数，只含有2个参数，能够较好拟合股票收益率分布的尖峰厚尾偏倚特性，给进一步的研究证券投资组合和金融风险管理带来了很大的便利。

把它们描述成不健康的放肆——无论是直白的性、暴力或是情感，或者说它们是糟糕的变态——无论是受虐狂或是施虐狂，这样做都没有说出它们对解决文化问题的作用。

Then the explicit expression of it under exponential claims and the differential equation are obtained.Thus we discuss the effects of credit and debit interests on it through data analysis. Through the research of the mean,the moment generating function and the higher moments of discounted aggregate dividend payments,we discuss the optimal dividend payments problems.

而对于Gerber-Shiu函数的研究，则是通过随机过程及随机微分方程的知识得到它满足的积分-微分方程及边值问题，然后得到了它在指数索赔下的明确表达式以及Erlang(2)索赔下满足的微分方程，并通过数值分析得到贷款利息及存款利息对它的影响。
