uva 106 这题说的是 说计算 x^2 + y^2  =  z^2  xyz 互质 然后计算个数和 在 N内 不在 勾股数之内的数的个数 然后去找需要的 维基百科上 看到 另 n*m*2 =b     n*n+m*m=c  m*m-n*n = a  m>n 然后这样可以计算出 所有互质的 勾股数 然后进行枚举n和m 进行判断 还有一个问题他为什么不会遗漏 互质的勾股数呢   我自己想了一下 应该是这样的  也就是说 n^2 和 m^2  必须为整数 就是说 他们是分数已经不可能了 那现在来讨…

最近以来,我使用d3进行我的可视化工具的开发已经3个月了,同时也兼用其他一些图表类库,自我感觉稍微有点心得.之前我也写过相关文章,我涉及的数据可视化的实现技术和工具,但是那篇文章对于项目开发而言太浅了.于是想写关于d3进行项目实战的系列文章,就像我之前的angularjs实战系列文章一样把整个开发过程中遇到的各种问题及解决办法梳理成章,以为留存.作为开篇,我还是想先把这段时间来我一直参考的资料做一个整理,并谈一些宏观的体会. 一.前方有坑,注意! ————————————————————————…

摘要 随着信息技术的不断发展,人类可以很容易地收集和储存大量的数据,然而,如何在海量的数据中提取对用户有用的信息逐渐地成为巨大挑战.为了应对这种挑战,数据挖掘技术应运而生,成为了最近一段时期数据科学的和人工智能领域内的研究热点.数据集中的频繁模式作为一种有价值的信息,受到了人们的广泛关注,成为了数据挖掘技术研究领域内的热门话题和研究重点. 传统的频繁模式挖掘技术被用来在事务数据集中发现频繁项集,然而随着数据挖掘技术应用到非传统领域,单纯的事务数据结构很难对新的领域的数据进行有效的建模.因此,频繁…
