An estimate of the Hessian of the Lagrangian is updated at each iteration using the BFGS formula.

由于自变量的维数很高，这样的问题是被分解成多个低维子问题来求解的。

Recently, it is a hot research at home and abroad in portioning groups of the matrix to iteration which is based on the structure of the Hessian.

近年来，结合稀疏Hesse阵的结构，按照分划组的思想将矩阵列分划进行迭代是国内外研究的一个热点。

In Chapter 4 we discuss the solvable theorem of adaptive inverse optimal control problems, and proceed with controller designs of global asymptotic stability in probability, adaptive inverse optimal stabilization in probability and output-feedback adaptive inverse optimal stabilization in probability for strict-feedback stochastic nonlinear continuous systems with additive standard Wiener noises and constant unknown parameters using It〓's differentiation rule and an adaptive backstepping algorithm. Control laws and adaptive laws can be obtained at one time by this design scheme. Many simulations have been performed to validate the properties of the proposed adaptive control scheme.

在第4章中，针对具有标准Wiener噪声扰动和未知定常参数的不确定随机非线性系统，提出并证明了自适应逆最优控制问题可解定理，构造了适当形式的四次型随机控制Lvapunov函数，基于It〓微分规则和自适应Backstepping算法，系统地设计了全局依概率渐近稳定控制器、自适应逆最优控制器、输出反馈逆最优控制器以及在设计中如何处理二阶Hessian矩阵函数的方法，这种方法可同时获得控制律和自适应律，通过实例仿真，表明该控制算法是有效性的。

In Chapter 4, a symmetric triangular partitioned secant method for solving large scale sparse unconstrained optimization problems is constructed, which is a combination of a secant method and a finite difference method, and depends on a consistent partition of the columns of the lower triangular part of the Hessian matrix; it reduces the number of gradient evaluations required by Powell and Toints algorithm (the indirect lower triangular substitution algorithm) by one at every iterative step.

此算法是基于稀疏Hesse阵的下三角部分的列的相容分划的基础上建立起来的，把割线法和有限差分法有机的结合在了一起，在每次迭代中，把由Powell和Toint的算法所需要的梯度赋值次数减少了一。

That calm profile under the little three-cornered hat of the school of Brienne, that green uniform, the white revers concealing the star of the Legion of Honor, his great coat hiding his epaulets, the corner of red ribbon peeping from beneath his vest, his leather trousers, the white horse with the saddle-cloth of purple velvet bearing on the corners crowned N's eagles, Hessian boots over silk stockings, silver spurs, the sword of Marengo,--that whole figure of the last of the Caesars is present to all imaginations, saluted with acclamations by some, severely regarded by others.

布里埃纳①军校的小帽下那种镇静的侧面像，那身绿色的军服，遮着勋章的白翻领，遮着肩章的灰色外衣，坎肩下的一角红丝带，皮短裤，骑匹白马，马背上覆着紫绒，紫绒角上有几个上冠皇冕的N和鹰，丝袜，长统马靴，银刺马距，马伦哥剑，在每个人的想象中都有着这副最后一个恺撒的尊容，有些人见了欢欣鼓舞，有些人见了侧目而视。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
