说明：  使用python实现计算器，基本实现计算器所需要的全部功能，非常适合用来测试(operator, Out-of-Sample Equity Premium Prediction: Combination Forecasts and Links to the Real Economy)

车辆线性二自由度模型,非常好的simulink仿真模型(Vehicle linear two degree of freedom model, very good Simulink simulation model.)

说明：  模拟退火是 80 年代初发展起来的一种随机性组合优化方法。它模拟高温金属降温的热力学过程，并广泛应用于组合优化问题。基于模拟退火的粒子群优化算法是把模拟退火机制引入基本粒子群优化算法中，采用杂交粒子群优化算法中的杂交运算和带高斯变异的粒子群优化算法中的变异运算，以便进一步调整优化群体。(Simulated annealing is a stochastic combinatorial optimization method developed in the early 1980s. It simulates the thermodynamic process of high temperature metal cooling and is widely used in combinatorial optimization problems. The particle swarm optimization algorithm based on simulated annealing introduces the simulated annealing mechanism into the basic particle swarm optimization algorithm, and adopts the hybrid operation in hybrid particle swarm optimization algorithm and the mutation operation in particle swarm optimization algorithm with Gaussian mutation, so as to further adjust the optimization population.)

说明：  熵权法解决评价类问题，注释详细，可修改，可套用(Entropy weight method to solve evaluation problems, detailed annotations, can be modified)

这是几个游泳的测试程序，都是些基础的东西，有带学习 -This is a swim test procedure are some basic things, the learning

PIC 18F4550 BASIC LED CODE

一个普通的小游戏，没有什么功能，就一个小游戏(An ordinary little game, no function, just a junk game)

说明：  pwm0到10v调光，N76003的相关资料ADC多通道采集，PWM自动调光(Pwm0 to 10v dimming, multi-channel ADC acquisition of N76003 related data, PWM automatic dimming)
