比如每个企业和个人都要考虑的一个问题“在一定成本下，如何使利润最大化”等。最优化方法是一种数学方法，它是研究在给定约束之下如何寻求某些因素(的量)，以使某一(或某些)指标达到最优的一些学科的总称。随着学习的深入，博主越来越发现最优化方法的重要性，学习和工作中遇到的大多问题都可以建模成一种最优化模型进行求解，比如我们现在学习的机器学习算法，大部分的机器学习算法的本质都是建立优化模型，通过最优化方法对目标函数（或损失函数）进行优化，从而训练出最好的模型。常见的最优化方法有梯度下降法、牛顿法和拟牛顿法、共轭梯度法等等。
For example, every enterprise and individual should consider a problem "how to maximize profit at a certain cost." The optimization method is a mathematical method. It is a general term for some disciplines that study how to find certain factors (quantity) under a given constraint to make one (or some) index get the best. With the in-depth study, the blogger found more and more importance of optimization methods, have to study and work in most of the problems can be modeled as solving an optimization model, such as we are now learning machine learning algorithm, most of the machine learning algorithm is the essence of optimization model is established through the optimization method of the objective function (or the loss function) optimization, to train a best model. The common optimization methods include gradient descent method, Newton method and quasi Newton method, conjugate gradient method and so on. (2018-01-29, Visual Basic, 1KB, 下载7次)

这个程序只合适计算k=1 (也就是Lcd=1）,对于其他k值，一些参数要做适当变化。这也是soliton format 不宜用于非线性耦合开关的一个原因。它使问题复杂化。这个程序是计算孤子格式化下的非线性薛定格方程组，程序中的方程与我们之前的博文提供的程序的方程不同。我们当初做这个仿真的目的，一方面要重复 S. Trillo, S. Wabnitz, E. M. Wright and G. I. Stegman, 在他们论文“Soliton switching in fiber nonlinear directional couplers.” Opt. Lett. Vol.13, No.8, pp672-674(1988) 的仿真结果，以确保我们程序是正确的。另一方面要以己之矛攻己之盾。当时，孤子开关用孤子归一化的非线性薛定格方程描述已经广泛被接受和使用。很多人因为他们孤子开关的工作，也获得了重要的学术地位，要想发一篇跟他们之前的工作不同的观点的文章是很困难的。那些审稿的人，不是他们本人，就是学生或粉丝。图1中的曲线跟我们其它文中的曲线有很大不同，这是因为在这里输入脉冲是bsech(bt),因而输入脉冲的脉宽跟脉冲幅度一起变化，而其他地方我们只考虑脉冲幅度的变化，因为脉宽的变化已经包含在参量Lcd 中了。
