Furthermore, the first-order optimality condition and its equivalent reformulations for generalized semi-infinite max-min programming with a non-compact set are presented using the lower-Hadamard directional derivative and subdifferential.2. Chapter 3 studies the gradient-type methods for unconstrained optimization problems. Section 1 proposes a new class of three-term memory gradient methods. The global convergence property of the method is established. Furthermore, in order to improve the convergence property of the method, a new class of memory gradient projection methods is presented with the property that the whole sequence of iterates converges to a solution to the problem under the conditions such as pseudo-convexity and continuous differentiability of objective function. In section 2, two new classes of methods, called gradient-type method with perturbations and hybrid projection method with perturbations, are proposed. In these methods, non-monotone line search technique is employed, which makes them easily executed in computer.

第3章研究了无约束优化问题的梯度型算法，第1节提出了一类新的三项记忆梯度算法，讨论了算法的全局收敛性，进一步提出了一类新的具有更好收敛性质的记忆梯度投影算法，并证明了该算法在函数伪凸的情况下具有整体收敛性，第2节在非单调步长搜索下提出了带扰动项的梯度型算法及其混合投影算法，这两类算法的一个重要特征就是步长采用线搜索确定而不象许多文献中那样要求步长趋于零，这样更容易在计算机上实现，在较弱的条件下证明了这些算法的全局收敛性，数值算例表明了算法的有效性。

Chaos is a dynamic and species-random and nonlinear system, and it has sensitive initial conditions, continuous power spectrum and traversal, so it is often used to generate pseudo-random sequence.

由于混沌是一种动态的、类随机的非线性系统，且具有对初始条件敏感、连续的功率谱、各态遍历等特性，因此可产生伪随机序列。

Unfortunately, a good skills too early, but from now on will look at the skills丐帮only ranked fourth, and other door-to-door now had their own strong indeed significantly weaker, the beggar is a pseudo-control door-to-door, with hidden weapon dabbler still, it is estimated that Pa has seen a knife, he switched to the door, and prices are not good short-term, medium-difficult, and the latter may be the rise of - Oh, sigh.

丐帮：停牌。45技能不错可惜出得太早了，不过从现在来看丐帮的技能也就只能排第四，其他门派如今变强了自己确实显弱了，乞丐是个伪控制门派，有了暗器也还是半吊子，估计霸刀也看出端倪，改投他门了，短期行情不妙，中期难做，后期可能会崛起--唉，一声叹息。

This paper introduces a single-carrier system with hybrid time-frequency domain Decision Feedback Equalization, in which the short pn (Pseudo-Noise) sequence with fixed waveform replaces the cyclic prefix in the conventional Single Carrier systems with Frequency Domain Equalization, and the long PN sequences composed of several short pn sequences are employed as the channel training sequences to complete the initial estimation and tracking for fast-varying channel.
