无约束的

In chapter 2,by referring to the algorithm in paper[7],we present a class of conjugate gradient methods connected with Hestenes-Stiefel Algorithm.

在第一章中，我们首先简要的介绍了最优化问题的提出以及判断最优解常用的最优性条件；回顾了求解无约束优化问题常用的几类导数下降类算法。

That is, direct search methods for unconstrained optimization depend on the objective function only through the relative ranks of a countable set of function values.

那就是说，无约束优化的直接搜索法仅仅依赖于通过可数集的函数值的相关阶的目标函数。

Second, the van der Waals type cubic equation of state was used to calculate the critical pressure of the binary systems. By introducing the temperature and acentric factor into the mixing rule of attractive part of the equation of state, a new expression was set up.

对实验数据和文献数据的计算结果令人满意，并按照无约束条件最优化得到了相互作用参数表达式的系数值，更加说明本文建立的相互作用参数表达式是正确的和有一定理论基础的。

Utilize network , formate different area existing resource that material object exist one have enclosure , get involved , surmount temporary network that space restrain from not to organize limitlessly exactly rapidly, realize the resource-sharing , mutual supplement with each other ' s advantages of the technology , fund and talent, meet the fictitious operation that market demand puts out high quality , low cost products at fastest speed, such fictitious operation has been produced and managed fictitiously.

利用网络，把不同地区现有实物存在的资源迅速整合成一种无围墙、无限介入、超越空间约束的临时网络组织，实现技术、资金与人才的资源共享、优势互补，以最快的速度适应市场需求推出高质量、低成本产品的虚拟运作，这种虚拟运作产生了虚拟管理。

LC1 unconstrained optimization problem was discussed in the second chapter, giving a new trust region method and proving its global convergence and superlinear convergence under some mild conditions .

第二章讨论了LC~1无约束优化问题。给出了一个新的信赖域算法，并在一定的条件下证明了算法的全局收敛性和局部超线性收敛性。

The algorithm handles the objective function and constraints separately, and adopts both directional and random search mechanism. It can avoid falling into local optimal point, which may appear in previous bionics random algorithms due to uncertainness of some parameters and/or without guiding search direction.

该算法将目标函数与约束条件分开处理，采用兼具方向性和随机性的搜索机制，避免了已有仿生类算法由于一些参数难以确定和无引导性的搜索方向而陷入局部最优的问题。

The problem of solving linear equations changed equivalently into the problem of searching the minimum of unconstrained optimizations of function by variation principle in the paper.

首先通过变分原理将求解线性方程组的问题转化为等价的求解无约束函数最优化问题的极小值。

Different from traditional data bases, data streams have the following distinguished characteristics:(1)unbounded volume of data;(2)rapid arriving rate of data;(3)uncontrollability of tuples\' arriving order;(4) being processed only once for each tuple, except being reserved.

与传统数据库不同，数据流具有如下特点：(1)数据总量的无限性；(2)数据到达的快速性；(3)数据到达次序的无约束性；(4)除非可以保存，每个元素均只能被处理一次。

In viewpoint of the lack of enough basic data of foreign oilfields, under the conditions of insufficient core data, no constrains of seismic interpreted cross and fault data, the rational fine 3D geological model has been established by fine oil reservoir characterizing technique including the contrast results of individual layers, second well logging interpretation and so on.

针对国外油田多数基础资料不全，必须在缺乏取心资料，无地震解释层面及断层数据约束的条件下，运用层序地层学小层对比结果和二次测井解释等精细油藏描述技术，并插入虚拟井控制井间构造，进而建立了合理的精细三维地质模型，为该油田的储层预测及数值模拟提供了基础数据，并在实际应用中取得了良好效果。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
