最优化方法两阶段法与单纯形法matlab代码(Optimization method, two stage method and simplex method)

条码仓库管理系统，特别适合中小型超市，解决了库存、入库、出库、库存查询、数据报表等大量人工需要完成的事情，现在只需要轻轻的点几下鼠标就能完成，大量节约了人力和物力，实现了无纸化的操作，能把出库入库报表打印出来或导出为excel，更加直观和省时。(Bar code warehouse management system, especially suitable for small and medium-sized supermarkets, has solved a large number of manual tasks such as inventory, warehousing, warehousing, inventory query, data report forms and so on. Now it can be accomplished with a few clicks of the mouse. It saves a lot of manpower and material resources, realizes paperless operation, and can print out or export the warehouse report forms into excel, which is more intuitive and more intuitive. Time saving.)

这是一个用simpack已经搭建好的客车模型(this is a train model in simpack)

模拟实现了银行系统的各种业务，转账 存款 取款 修改密码等(Simulated realization of various business of banking system)

这是我在网络编程课上做的项目

这是我在大学二年级学习C语言课程时，作为“练笔”而编写的一个小程序（当时在我眼里可却是一个大程序！）其主要特点有：1、正真做到了全中文界面（不需要UCDOS操作系支持） 2、大量的图形特技（如图像的显隐技术、图像穿插技术、多任务仿真技术等） 3、纯C语言打造（不含任何C++知识） 4、实现了街机“俄罗斯方块”绝大部分功能（如动画、声音、速度变化） 5、用户可根据自据的习惯自由地调整“游戏操作键” 6、方法独特，全部语句和技术都是我本人原创，没有参考过任何相关代码 7、防“跟踪调试”技术，防“版权篡改”技术 8、

牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)

说明：  求解数独，根据递归唯一余数法和摒除法求解，如果无法解决在递归假设法求解。(Solving Sudoku is based on recursive unique residue method and elimination method, if it can not be solved by recursive hypothesis method.)
