    一:需求分析 1. 问题描述 魔王总是使用自己的一种非常精练而抽象的语言讲话,没人能听懂,但他的语言是可逐步解释成人能听懂的语言,因为他的语言是由以下两种形式的规则由人的语言逐步抽象上去的: ----------------------------------------------------------- (1) a---> (B1)(B2)....(Bm) (2)[(op1)(p2)...(pn)]---->[o(pn)][o(p(n-1))].....[o(p1)o] ----------------------------------------------------------- 在这两种形式中,从左到右均表示解释.试写一个魔王语言的解释系统,把 他的话解释成人能听得懂的话. 2. 基本要求: 用下述两条具体规则和上述规则形式(2)实现.设大写字母表示魔王语言的词汇 小写字母表示人的语言的词汇 希腊字母表示可以用大写字母或小写字母代换的变量.魔王语言可含人的词汇. (1) B --> tAdA (2) A --> sae 3. 测试数据: B(ehnxgz)B 解释成 tsaedsaeezegexenehetsaedsae若将小写字母与汉字建立下表所示的对应关系,则魔王说的话是:"天上一只鹅地上一只鹅鹅追鹅赶鹅下鹅蛋鹅恨鹅天上一只鹅地上一只鹅". | t | d | s | a | e | z | g | x | n | h | | 天 | 地 | 上 | 一只| 鹅 | 追 | 赶 | 下 | 蛋 | 恨 |

  • 非常好的优化算法的书

    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.

  • Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features:

    Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features: * Creates a virtual encrypted disk within a file and mounts it as a real disk. * Encrypts an entire partition or storage device such as USB flash drive or hard drive. * Encrypts a partition or drive where Windows is installed (pre-boot authentication). * Encryption is automatic, real-time (on-the-fly) and transparent. * Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: 1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data). * Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS. Further information regarding features of the software may be found in the:http://www.truecrypt.org/

  • 本代码为编码开关代码

    本代码为编码开关代码,编码开关也就是数字音响中的 360度旋转的数字音量以及显示器上用的(单键飞梭开 关)等类似鼠标滚轮的手动计数输入设备。 我使用的编码开关为5个引脚的,其中2个引脚为按下 转轮开关(也就相当于鼠标中键)。另外3个引脚用来 检测旋转方向以及旋转步数的检测端。引脚分别为a,b,c b接地a,c分别接到P2.0和P2.1口并分别接两个10K上拉 电阻,并且a,c需要分别对地接一个104的电容,否则 因为编码开关的触点抖动会引起轻微误动作。本程序不 使用定时器,不占用中断,不使用延时代码,并对每个 细分步数进行判断,避免一切误动作,性能超级稳定。 我使用的编码器是APLS的EC11B可以参照附件的时序图 编码器控制流水灯最能说明问题,下面是以一段流水 灯来演示。
