Exceptional C++ shows by example how to go about solid software engineering. Along with a lot of other material, this book includes expanded versions of the first 30 issues of the popular Internet C++ feature Guru of the Week (or, in its short form, GotW), a series of self-contained C++ engineering problems and solutions that illustrate specific design and coding techniques.

资源描述实现Apriori算法，应用于如下的数据（给定参数），挖掘频繁项集   -an example for Apriori algorithm in data mining

差分进化算法（DE）  由Storn和Price与1995年首次提出。算法起初是寻求解切比雪夫多项式拟合问题，由于该问题是一个实数拟合优化问题，因此两人采用实数编码直接表示个体，同时用向量差分来对向量群体进行扰动。据此提出的差分变异算子成为算法的主要的遗传操作。

用三元组表示稀疏矩阵,可以转置 加法，减法，乘法，求逆。- With three Yuan groups expressed the sparse matrix, may transpose the addition, the subtraction, the multiplication, asks to go against.

常用算法分析，不用我多说，这绝对是编程的最基本要求-Common algorithms for analysis, I do not have to say, this is absolutely the most basic requirement of programming! ! !
