最小二乘法拟合圆vc实现，最小二乘法(least squares analysis)是一种 数学 优化 技术，它通过 最小化 误差 的平方和找到一组数据的最佳 函数 匹配。 最小二乘法是用最简的方法求得一些绝对不可知的真值，而令误差平方之和为最小。(least squares fitting round vc realized, least-squares method (least squares analysis) is a mathematical optimization techniques, It error by minimizing the square and a group of data to find the best matching function. Least-squares method is the most simple method to derive absolutely true value unknown, and so the sum of squared errors to the minimum.)

哈夫曼编码译码系统，设置发送者和接受者两个功能， 发送者的功能包括： ①输入待传送的字符信息； ②统计字符信息中出现的字符种类数和各字符出现的次数（频率）； ②根据字符的种类数和各自出现的次数建立哈夫曼树； ③利用以上哈夫曼树求出各字符的哈夫曼编码； ④将字符信息转换成对应的编码信息进行传送。 接受者的功能包括： ①接收发送者传送来的编码信息； ②利用上述哈夫曼树对编码信息进行翻译，即将编码信息还原成发送前的字符信息。 (Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)
