A program to demonstrate the optimization process of particle swarm optimization. A two-dimensional objective function is visualized by level of grey: the lighter the color, the higher the function value. The particles are shown as red circles, their trajectory as red lines.-A program to demonstrate the optimization process of particle swarm optimization.

遗传算法在运行早期个体差异较大，当采用经典的轮盘赌方式选择时，后代产生的个数与父个体适应度大小成正比，因此在早期容易使个别好的个体的后代充斥整个种群，造成早熟。在遗传算法后期，适应度趋向一致，优秀的个体在产生后代时，优势不明显，从而使整个种群进化停滞不前。因此对适应度适当地进行拉伸是必要的，这样在温度高时(遗传算法的前期)，适应度相近的个体产生的后代概率相近；而当温度不断下降后，拉伸作用加强，使适应度相近的个体适应度差异放大，从而使得优秀的个体优势更明显。由于模拟退火算法和遗传算法可以互相取长补短，因此有效地克服了传统遗传算法的早熟现象，同时根据聚类问题的具体情况设计遗传编码方式、适应度函数，使该算法更有效、更快速地收敛到全局最优解。本案例研究了基于遗传模拟退火算法的聚类算法。

使用C++实现的Graham扫描法（求解凸包问题），可设置生成随机点的个数、样式，同时支持设置显示范围、显示算法处理时间及使用文件导入导出点等功能。（文件格式为，头四个字节是点的个数，以后分别是各个点的x坐标和y坐标，每个数值均占4字节）。-The use of C++ Realize the Graham scan method (for solving convex hull problems), can be set to generate a random number of points, patterns, and at the same time to support the set display range, display algorithm processing time and the use of document features such as import and export points. (File format for the first four bytes is the number of points, after all points are x coordinates and y coordinates, each account for 4-byte value).
