万有引力单目标优化算法，用于单目标线性规划问题(Universal gravitation single objective optimization algorithm is used for single target linear programming problem.)

一元稀疏多项式编程，希望对大家的编程有点用，欢迎下载(hope it useful to you)

利用Python实现特征的MinMax标准化和Z-Score标准化两种特征归一化方法。并用原特征、两种归一化特征分别进行朴素贝叶斯模型训练，比较模型性能。(Two normalization methods of MinMax normalization and Z-Score standardization are implemented by Python. The naive Bayes model is trained with the original features and two normalization features respectively to compare the performance of the model.)

一个简单的网格生成程序，操作方便，易学，类似于easymesh！(A simple grid generation program, easy to operate, easy to learn, like easymesh!)

matlab计算的自适应阈值分隔，非常好用，适用于初学者(matlab adaptive threshold calculation separated, very useful for beginners)

基于前推回代法的电力系统潮流计算程序。 需要输入支路阻抗和节点功率矩阵。包括支路号、首节点号、尾节点号、支路自阻抗、尾节点给定功率。 输出各节点的电压幅值、相角和各支路电流。(Power flow calculation program based on the forward and backward substitution method. Need input the branch impedance node power matrix. Including branch number, node number, the tail node number, branch self-impedance tail node given power. The output node voltage amplitude, phase angle and current of each branch.)

有限元法计算程序，运用三角单元，进行线性插值，处理平面问题。(finite element method)
