资源描述根据Hopfield神经网络相关知识，设计了一种具有联想记忆功能的离散型Hopfield神经网络。要求该网络可以正确地识别0~9这10个数字，当数字被一定的噪声干扰后，仍具有较好的识别效果，仿真测试结果表明该设计可行有效。

有效的调度方法与优化技术的研究和应用，对于制造企业提高生产效率，降低生产成本等方面起着重要作用。然而柔性车间调度问题计算复杂，约束条件多，普通算法容易陷入局部最优问题。免疫算法是模仿免疫系统抗原识别，抗原与抗体产生过程，并利用免疫系统多样性和记忆抽象得到的算法，具有非线性，全局化搜索等优势，本案例研究了基于免疫算法的柔性车间调度算法。

简单的讲，所谓拟合是指已知某函数的若干离散函数值{f1,f2,…,fn}，通过调整该函数中若干待定系数f(λ1, λ2,…,λ3), 使得该函数与已知点集的差别(最小二乘意义)最小。如果待定函数是线性，就叫线性拟合或者线性回归(主要在统计中)，否则叫作非线性拟合或者非线性回归。表达式也可以是分段函数，这种情况下叫作样条拟合。-Simply speaking, the so-called fitting refers to a function known to a number of discrete function values (f1, f2, ..., fn), by adjusting the number of undetermined coefficient function f (λ1, λ2, ..., λ3), makes the function and known points of difference (least squares significance) the smallest. To be determined if the function is linear, is called linear regression or linear regression (mainly in the statistics), otherwise known as non-linear fitting, or nonlinear regression. Expressions can also be a sub-function, this case is called spline fitting.

行编辑算法：可将输错的单个字符删除，也可将又错误的一行字符删除。操作简便。用栈来实现上述功能。-line editor algorithm : can be wrong deletion of a single character, and it can also wrong to delete his characters. Easy to operate. Stack used to achieve the above functions.
