利用表达式求解和栈的只是，设计一个简易的数学题库， 可供小学生作业，并能给出分数。 要求：建立试题库文件，随机产生 n 个题目；题目涉及加减乘除，带括弧的混合运算；随时可以退出；保留历史分数，能回顾历史，给出与历史分数比较后的评价。(Use solving expressions and stack just design a simple math exam, students for the job, and can give a score. Requirements: Create test file, randomly generating n topics topics involving addition, subtraction with parentheses mixing operation ready to quit keep historical scores, can look back at history, and history is given uation scores after comparison.)

说明：  使用分布傅立叶法计算非线性薛定谔方程。可以得到光纤非线性传输特性。(Fourier method using the distribution of nonlinear Schr枚dinger equation. Can be non-linear optical transmission characteristics.)

说明：  利用MATLAB实现了16位快速傅立叶变换，并与自包含函数进行了比较。(The 16-bit Fast Fourier Transform is realized by using MATLAB and compared with the self-contained function.)

用Python语言写的多目标进化算法库（2017年最新版本），包含常见的多目标进化算法以及当前最新文献中的最新算法，能够实现不同算法之间的性能比较（包含常见的GD, IGD, HV等评价指标自动生成）。可以供进化计算、多目标优化、单目标优化算法的学习参考。Python语言版本简单易懂，实用性强。(Library of multi-objective evolutionary algorithm written in Python language (the latest version in 2017), including multi-objective evolutionary algorithm and the most common new literature in the new algorithm, can realize the performance between different methods (including the common GD, IGD, HV and other evaluation index generation). It can be used as a reference for evolutionary computation, multi-objective optimization and single objective optimization. Python language version is simple and easy to understand, practical.)
