问题描述 设有n种不同面值的硬币，各硬币的面值存于数组T[1:n]中。现要用这些面值的硬币来找钱，可以实用的各种面值的硬币个数不限。当只用硬币面值T[1],T[2],…,T[i]时，可找出钱数j的最少硬币个数记为C(i,j)。若只用这些硬币面值，找不出钱数j时，记C(i,j)=∞。 &#61611 编程任务 设计一个动态规划算法，对1≤j≤L，计 ...

AES在AVR单片机上的实现 资源要求 Program: 4492 bytes (6.9％ Full) (.text + .data + .bootloader) Data: 745 bytes (9.1％ Full) (.data + .bss + .noinit) 可以在AVR Studio中模拟运行 AES加密和解密 在AVR Studio 中模拟运行 Ctrl+F7 后，模拟执行到main入口处 按F5后, 知道到加密完成 可以看出加密的结果 再按 ...

对任意给定的文法G 构造LR(1) 项目集规范族，其中要实现CLOSURE(I)、GO(I,X)、FIRST 集合等。在此基础上， 构造了LR（1）分析表。然后对输入的句子进行语法分析，给出接受或出错报告。 程序采用文件输入输出方式。其中包括两个输入文件：文法grammar.txt，以及 输入串input.txt；两个输出文件：项目集items.txt 和文法的LR( ...

基于S3C2440的四线电阻式触摸屏驱动程序，linux2.6.22内核。把touchscreen.c放在driver/input/touchscreen/下。修改arch/arm/mach-s3c2440/mach-smdk2440.c以及相应的Makefile加上驱动即可。

Advanced UNIX Programming is the long-awaited (19 years!) update to the 1985 original. Maybe "update" isn t the right word--of the 750-or-so pages in the new book, there are maybe two dozen paragraphs that are unchanged. The original covered about 70 system calls, and the new one covers about 300. ...

非常好的优化算法的书，详细介绍了蚁群算法和粒子群算法以及相关的matlab工具箱，讲了理论和应用给出了工具箱的下载地址。 Swarm intelligence is an innovative computational way to solve hard problems. In particular, particle swarm optimization, also commonly known as PSO, mimics the behavior of a swarm of i ...

This article introduces how to construct a Hospital Ward Information System with three-tiered technology. The System applies to UML, BDE, MIDAS, distributed compute theory and a special architecture to make such functions: patients check in and check out, prescription input, drug-delivery at center ...

This application report presents basic code for initializing and operating the TMS320LF240x DSP devices. Two functionally equivalent example progra ms are presented: one written in assembly language and the other in C language. Detailed discussions of each program are provided that explain numerous ...
