本文提出了一种基于独立分量分析的音频数字水印方法。嵌入水印时,对原始音频文件进行一级小波分解,在分解 得到的逼近分量中利用随机混合方法嵌入水印后进行小波逆变换形成嵌入水印的音频文件。仿真实验结果表明这种方 法的强鲁棒性和可行性。(Abstract:Audio p roduction is one of the important digital multimedias, which transmit becomes more and more convenient. To p revent the multimedia content from being stolen or illegally used, audio content p rotection techniques become increasingly impor2 tant so that the potential of these app lications can be reached. As the importantmethod of copyright p rotection, the digitalwater2 marking technology has been acquired widely recognition and research. This paper p resents a method of digital audio watermark2 ing based on independent component analysis. When embedding watermarking, the original audio is decomposed by single2level discrete 12D wavelet transform, watermarking is embedded by mixing randomly to the app roximation coefficient vector obtained, and the audio is single2level reconstructed receiving audio havingwatermarking. Emulated experiment results show that thismeth2 od is robust and feasible.)

求从1到20的阶乘，并且可以推广到N阶阶乘，。(Demand from 1 to 20 factorial, and can be extended to N-order factorial,.)

遗传算法可用于优化计算，C++，lingo都可用(Genetic algorithms can be used for optimization, C++, lingo are available)

说明：  足球联赛采用主客场双循环赛制，胜一场得3分，平局各得1分，负一场得0分，联赛排名以积分多者在前，当两队（或多队）积分相同时，则净胜球（即进球数与失球数之差）多者在前，若净胜球相同，则进球数多者在前，若仍相同，则抽签或踢附加赛决定名次（这在联赛结束后进行，联赛未结束则两队名次并列，本程序不做这方面要求）。试编一程序统计最近一轮比赛后，各队积分及排名。(SOCCER PLAYER)
