引入能直接处理连续型数据的邻域粗糙集约简模型，给出一种基于邻域粗糙集模型和粒子群优化的特征选择算法。仿真实验结果表明该算法可以选择较少的特征，改善分类的能力。(employs the neighborhood rough set reduction model which can process the numerical features directly without discretization. Then the particle fitness function in particle swarm optimization (PSO) algorithm is built based on that model. Finally, a novel feature selection algorithm based on particle swarm optimization and neighborhood rough set reduction model is proposed. Experimental results prove that the new algorithm improves classification ability with fewer features selected.)

ARM Cortex-M3与Cortex-M4权威指南(第3版)
说明： 共3部分，1/3
本书介绍了ARM架构的背景知识以及指令集、中断处理等处理器特性，并描述了如何设置并利用存储器保护单元(MPU)等可用的高级特性。书中论述Keil MDK、IAR EWARM、gcc以及CooCoxCoIDET工具入门的章节可以给初学者在编写程序代码方面提供一些帮助，其中也包括一些重要的软件开发问题，比如低功耗特性的使用、信息输入/输出的处理、汇编和c语言的混合编程及其他高级技术话题。(This book introduces the background knowledge of arm architecture, instruction set, interrupt processing and other processor features, and describes how to set up and utilize the available advanced features such as memory protection unit (MPU). The chapters on keil MDK, IAR EWARM, GCC and coocox coidet tools in the book can provide some help for beginners in writing program code, including some important software development problems, such as the use of low-power features, information input / output processing, mixed programming of assembly and C language, and other advanced technical topics.)

说明： 有一个长度为整数L(1<=L<=10000)的马路，可以想象成数轴上长度为L的一个线段，起点是坐标原点，在每个整数坐标点有一棵树，即在0,1,2，...，L共L+1个位置上有L+1棵树。
现在要移走一些树，移走的树的区间用一对数字表示，如 100 200表示移走从100到200之间（包括端点）所有的树。
可能有M(1<=M<=100)个区间，区间之间可能有重叠。现在要求移走所有区间的树之后剩下的树的个数。
输入：
两个整数L(1<=L<=10000)和M(1<=M<=100)。
接下来有M组整数，每组有一对数字。
输出：
可能有多组输入数据，对于每组输入数据，输出一个数，表示移走所有区间的树之后剩下的树的个数。(Has a length of integer L (1 < = L < = 10000) of the road, one can imagine a number line segment of length L, the starting point is the coordinate origin, each integer coordinate points in a tree, i.e. 0,1 , 2, ..., L total has L+1 L+1 positions on the tree. Now to remove some trees, tree removed by a range of digitally represented, such as 100 200 represents removed (inclusive) between 100 and 200 all the trees. There may be M (1 < = M < = 100) intervals, there may be overlap between the intervals. Now, after the number of trees require the removal of all remaining sections of the tree. Input: two integer L (1 < = L < = 10000) and M (1 < = M < = 100). Then there is an integer M groups, each with a pair of numbers. Output: there may be multiple sets of input data, for each set of input data, the output of a number indicating the number of the removal of all remaining sections of the tree after tree.)
