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)=∞。 编程任务 设计一个动态规划算法，对1≤j≤L，计算出所有的C( n,j )。算法中只允许实用一个长度为L的数组。用L和n作为变量来表示算法的计算时间复杂性 数据输入 由文件input.txt提供输入数据。文件的第1行中有1个正整数n（n<=13），表示有n种硬币可选。接下来的一行是每种硬币的面值。由用户输入待找钱数j。 结果输出 程序运行结束时，将计算出的所需最少硬币个数输出到文件output.txt中。

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F10,执行解密, 可以看出input数组恢复了 原来的结果

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(1)分析表 action_table.txt。由于语法分析的结果只给出接受或错误报告，比较简

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. （这是Advanced UNIX Programming的附书源码）

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 insects or a school of fish. If one of the particle discovers a good path to food the rest of the swarm will be able to follow instantly even if they are far away in the swarm. Swarm behavior is modeled by particles in multidimensional space that have two characteristics: a position and a velocity. These particles wander around the hyperspace and remember the best position that they have discovered. They communicate good positions to each other and adjust their own position and velocity based on these good positions.

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 pharmacy and information of patient manage with computer networking.

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 compiler and assembler directives, code requirements, and hardware-related requirements. The programs are ready to run on either the TMS320LF2407 Evaluation Module (EVM) or the eZdsp LF2407 development kit. However, they are also intended for use as a code template for any TMS320LF240x (LF240x) or TMS320LF240xA (LF240xA) DSP target system.
