旅行家问题 一个旅行家想驾驶汽车以最少的费yi 用从一个城市到另一个城市（假设出发时油箱是空的）。给定两个城市之间的距离为D1、汽车油箱的容量为C(以升为单位），每升汽油能行驶的距离为 D2，出发点每升汽油价格P和沿途油站数N（N可以为零），油站i离出发点距离Di,每升汽油价格Pi(i=1,2...N)。计算结果四舍五入至小数点后两位。 如果无法到达目的地，则输出“No Solution"。-issue a travel home to travel home to drive a car with the minimum of cost yi used from one city to another city (assuming starting at the fuel tank was empty). Given the two cities for the distance between D1, car fuel tank capacity of the C (in liters) per liter petrol traveling distance to the D2, the starting point liter gasoline prices P and several petrol stations along the N (N can be zero), PFS i distance from the starting point Di per liter Steam oil prices Pi (i = 1,2 ... N). Calculation results rounded to two decimal places. If unable to reach their destination, the export of "No Solution."

用来求解非线性系统中分岔,混沌,周期,准周期等动力学,可以求数值解,也可画图,只要知道系统模型,可以根据需要自由修改参数,软件带有使用说明,简单易懂-Used to solve nonlinear systems in the bifurcation, chaos, periodic, quasi-periodic dynamics, etc., you can seek numerical solutions, but also drawing, as long as know the system model, you can freely modify the parameters as needed, the software with instructions for use, simple and easy to understand

对数回归方程 LogarithmRegress.cs 方程模型为 Y=a*LnX+b public override double[] buildFormula() 得到系数数组，存放顺序与模型系数相反，即该数组中系数的值依次是b,a。 public override double forecast(double x) 预测函数，根据模型得到预测结果。 public override double computeR2() 计算相关系数（决定系数），系数越接近1，数据越满足该模型。 -Logarithmic regression equation LogarithmRegress.cs equation model for Y = a* LnX+ Bpublic override double [] buildFormula () get coefficient array, the storage order and model coefficients contrary, that is, the array is followed by the value of coefficient b, a. public override double forecast (double x) prediction function, according to the results of model prediction. public override double computeR2 () calculated the correlation coefficient (determination coefficient), coefficient of the closer one, the data satisfy the model more.
