Description: 贪心算法作业的解题报告(含证明)和源代码:磁盘文件最优存储问题，当初证明花了一些时间。问题描述：设磁盘上有n个文件，f1,f2,…,fn，，每个文件占磁盘上1个磁道。这n个文件的检索概率分别是p1,p2,…,pn,
且∑pi=1。磁头从当前磁道移到被检信息磁道所需的时间可用这2 个磁道之间的径向距离来度量。如果文件pi存放在第i道上, ，则检索这n 个文件的期望时间是∑pipjd(i,j)
其中d(i,j) 是第i道与第j 道之间的径向距离|i-j|。磁盘文件的最优存储问题要求确定这n个文件在磁盘上的存储位置，使期望检索时间达到最小。试设计一个解此问题的算法，并分析算法的正确性和计算复杂性。-Greedy algorithm for solving the report of operations (including certificate) and the source code: the optimal disk file storage issues, had spent some time to prove. Problem Description: There are n disk-based files, f1, f2, ..., fn,, accounts for each file on a disk track. This n the probability of a document retrieval are p1, p2, ..., pn,
And Σpi = 1. Head from the current track information to be seized can be used track the time required between these two tracks to measure the radial distance. Pi if the file stored in the first track i,, then retrieve documents that the expectations of n is Σpipjd (i, j)
Which d (i, j) is the first i Road with the first j of the radial distance between the Road | ij |. Optimal storage disk file to seek to establish that n files on the disk storage location, so expect to minimize search time. Try to design a solution algorithm for this problem and to analyze the correctness of algorithms and computational complexity.

Description: 8051实现直流电机PMW调速系统
本文所述的直流电机闭环调速系统是以低价位的单片微机8051为核心的，而通过单片机来实现电机调整又有多种途径，相对于其他用硬件或者硬件与软件相结合的方法实现对电机进行调整，采用PWM软件方法来实现的调速过程具有更大的灵活性和更低的成本，它能够充分发挥单片机的效能，对于简易速度控制系统的实现提供了一种有效的途径。而在软件方面，采用PLD算法来确定闭环控制的补偿量也是由数字电路组成的直流电机闭环调速系统所不能及的。曾经也试过用单片机直接产生PWM波形，但其最终效果并不理想，在使用了少量的硬件后，单片机的压力大大减小，程序中有充足的时间进行闭环控制的测控和计算，使得软件的运行更为合理可靠。-This article mainly introduces the method to generate the PWM signal by using MCS-51 single-chip computer to control the speed of a D.C. motor. It also clarifies the principles of PWM and the way to adjust the duty cycle of PWM signal. In addition, IR2110 has been used as an actuating device of the power amplifier circuit which controls the speed of rotation of D.C. motor. What’s more, tachogenerator is used in this system to measure the speed of D.C. motor. The result of the measurement is sent to A/D converter after passing the filtering circuit, and finally the feedback single is stored in the single-chip computer and participates in a PI calculation. As for the software, this article introduces in detail the idea of the programming and how to make it.
Key words: PWM signal tachogenerator PI calculation
