冈萨雷斯数字图像处理，北京大学的课程课件。(Gonzalez Digital Image Processing, Peking University courseware.)

指数平滑法是对时间序列进行预测常用的方法之一,其理论基础是趋势外延，即未来一定时期内事物在数量上的演变特征不脱离过去的发展趋势,预测值是以前所有观测值的加权和,且对不同的数据给予不同的权数,越近期数据给予越大的权数,越远期的数据给予越小的权数。(Exponential smoothing method is commonly used to predict the time series one of the ways, the theoretical basis of the trend of the extension, that is, a certain period of time what the next evolution in the number of characteristics are not out of the development trend of the past to predict the value of all previous observations is the weighted and, on different data and different weights given to more recent data to give greater weights, the more long-term data to give the smaller weights.)

实现基于加权最小二乘法的电力系统状态估计算法，以于老师写的书里面四节点算例仿真(Implementation based on weighted least-square method of power system state estimation algorithm, with the teacher wrote the book four node example simulation)

一个100*100的正方形，用半径为10的圆覆盖，随机在100*100的平面内放置圆心，问至少需要多少个圆，才能使得成功覆盖整个区域的概率在95 以上？并给出一个均匀随机放置装置的分布图。(A 100* 100 square, a circle with a radius of 10 covers, 100* 100 randomly placed on the center plane, and asked how many circles at least, to cover the entire area so the probability of success of 95 or more? And gives a uniform distribution of randomly placed devices.)
