代入法的启发示搜索 我的代码实现是：按照自然语言各字母出现频率的大小从高到低（已经有人作国统计分析了）先生成一张字母出现频率统计表（A）--------(e),(t,a,o,i,n,s,h,r),(d,l),(c,u,m,w,f,g,y,p,b),(v,k,j,x,q,z) ，再对密文字母计算频率，并按频率从高到低生成一张输入密文字母的统计表（B），通过两张表的对应关系，不断用A中的字母去替换B中的字母，搜索不成功时就回退，在这里回朔是一个关键。

《多传感器数据融合手册》 《Handbook of Multisensor Data Fusion》 作者: David L. Hall 定价: USD 199.95 出版社: CRC 出版年: 2001-06-20 简介 · · · · · · Multisensor data fusion is an emerging technology with important applications in both the military and civilian sectors, such as target recognition, robotics, medical diagnostics, and "smart" buildings. It draws on techniques from wide-ranging disciplines, including artificial intelligence, pattern recognition, and statistical estimation. This handbook is an up-to-date, comprehensive resource for data fusion system designers and researchers. Top experts in the field lead readers from a basic introduction and survey of data fusion technology to advanced mathematics and theory and to some very practical advice for systems implementers.

本题的算法中涉及的三个函数： double bbp(int n,int k,int l) 其中n为十六进制位第n位，k取值范围为0到n+7，用来计算16nS1，16nS2，16nS3，16nS4小数部分的每一项。返回每一项的小数部分。 void pi(int m,int n,int p[]) 计算从n位开始的连续m位的十六进制数字。其中p为存储十六进制数字的数组。 void div(int p[]) void add(int a[],int b[]) 这两个函数都是为最后把十六进制数字转换为十进制数字服务的。 最后把1000个数字分别存储在整型数组r[]中，输出就是按顺序输出该数组。

UC Library Extensions UnderC comes with a pocket implementation of the standard C++ libraries, which is a reasonably faithful subset. This documentation describes those UnderC functions and classes which are not part of the C++ standard. UC Library Builtin functions: Most of these are standard C functions, but there are a few unique to the UnderC system which give you runtime access to the compiler. You may evaluate expressions, execute commands, compile code, etc. * Expands the text in expr using the UnderC preprocessor, putting the result into buff. void uc_macro_subst(const char* expr, char* buff, int buffsize) * Executes a UC #-command, like #l or #help. uc_cmd() expects the name of the command, _without_ the hash, e.g. uc_cmd("l fred.cpp") or uc_cmd("help"). void uc_cmd(const char* cmd) * Evaluates any C++ expression or statement will return non-zero if unsuccessful.

Hidden_Markov_model_for_automatic_speech_recognition This code implements in C++ a basic left-right hidden Markov model and corresponding Baum-Welch (ML) training algorithm. It is meant as an example of the HMM algorithms described by L.Rabiner (1) and others. Serious students are directed to the sources listed below for a theoretical description of the algorithm. KF Lee (2) offers an especially good tutorial of how to build a speech recognition system using hidden Markov models.

两种解决方案 Richard just finished building his new house. Now the only thing the house misses is a cute little wooden fence. He had no idea how to make a wooden fence, so he decided to order one. Somehow he got his hands on the ACME Fence Catalogue 2002, the ultimate resource on cute little wooden fences. After reading its preface he already knew, what makes a little wooden fence cute. A wooden fence consists of N wooden planks, placed vertically in a row next to each other. A fence looks cute if and only if the following conditions are met: ?The planks have different lengths, namely 1, 2, . . . , N plank length units. ?Each plank with two neighbors is either larger than each of its neighbors or smaller than each of them. (Note that this makes the top of the fence alternately rise and fall.)

为研究棉田农药喷洒机器人导航路径识别方法, 以 自然环境下采集的棉田图像为研究背景, 在L ab 色彩空间 进行处理, 把棉株从土壤背景中识别出来。通过最大方差阈 值分割法将图像转化为二值图像, 并经过中值滤波去除噪 声。二值图像垂直方向投影做直方图, 利用波谷位置确定左 右垄分界线。根据左右垄棉株位置平均得到导航离散点, 通 过Hough 变换得到导航路径, 进而得到导航控制参数。利用 坐标系转换关系将图像坐标系中的导航信息转换到世界坐 标系, 从而控制机器人行走。基于A S2R 机器人对连续动态 图像进行分析, 该方法获得的导航参数是完全可行的。
