源代碼\用動態規劃算法計算序列關系個數 用關系"<"和"="將3個數a，b，c依次序排列時，有13種不同的序列關系： a=b=c,a=b<c,a<b=v,a<b<c,a<c<b a=c<b,b<a=c,b<a<c,b<c<a,b=c<a c<a=b,c<a<b,c<b<a 若要將n個數依序列，設計一個動態規劃算法，計算出有多少種不同的序列關系， 要求算法只占用O(n),只耗時O(n*n).

c語言版的多項式曲線擬合。 用最小二乘法進行曲線擬合. 用p－1 次多項式進行擬合，p<= 10 x,y 的第0個域x[0],y[0],沒有用，有效數據從x[1],y[1] 開始 nNodeNum,有效數據節點的個數。 b,為輸出的多項式系數，b[i] 為b[i-1]次項。b[0],沒有用。 b,有10個元素ok。

crc任意位生成多項式 任意位運算 自適應算法 循環冗余校驗碼(CRC，Cyclic Redundancy Code)是采用多項式的 編碼方式，這種方法把要發送的數據看成是一個多項式的系數 ，數據為bn-1bn-2…b1b0 (其中為0或1)，則其對應的多項式為： bn-1Xn-1+bn-2Xn-2+…+b１X+b０ 例如：數據“10010101”可以寫為多項式 X７+X４+X２+1。 循環冗余校驗CRC 循環冗余校驗方法的原理如下： (1) 設要發送的數據對應的多項式為P(x)。 (2) 發送方和接收方約定一個生成多項式G(x)，設該生成多項式 的最高次冪為r。 (3) 在數據塊的末尾添加r個0，則其相對應的多項式為M(x)=XrP(x) 。(左移r位) (4) 用M(x)除以G(x)，獲得商Q(x)和余式R(x)，則 M(x)=Q(x) ×G(x)+R(x)。 (5) 令T(x)=M(x)+R(x)，采用模2運算，T(x)所對應的數據是在原數 據塊的末尾加上余式所對應的數據得到的。 (6) 發送T(x)所對應的數據。 (7) 設接收端接收到的數據對應的多項式為T’(x)，將T’(x)除以G(x) ，若余式為0，則認為沒有錯誤，否則認為有錯。

This document outlines what is necessary to install and run the LEACH protocol on version 2.27 of ns2. At the time of this writing, this is the newest version of ns2. The LEACH implementation was written as a stand-alone application. Thus, in the past a version compiled for LEACH may or may not work for other protocols. In addition, the original version of LEACH was compiled for version 2.5b which is an outdated version of ns2.

Lua is a powerful, light-weight programming language designed for extending applications. It is also frequently used as a general-purpose, stand-alone language. It combines simple procedural syntax (similar to Pascal) with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, interpreted from bytecodes, and has automatic memory management with garbage collection, making it ideal for configuration, scripting, and rapid prototyping.

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

AutoBoot is a generic boot loader that automatically locates, loads, and executes object files from multiple types of media. AutoBoot provides a simple, fast, and functional means of loading an OS image while maintaining a small Flash memory footprint. This binary release contains a stand-alone version of AutoBoot for the DbAu1200 development board, designed to replace the YAMON boot loader.

Foundations of Python Network Programming leads readers through every aspect of client and server programming with Python. Python is a new and innovative scripting language. It is set to replace Perl as the programming language of choice for scripters and for serious application developers wanting a feature rich yet simple language to deploy their products in. This book features extensive examples that not only demonstrate important concepts and practices, but also provide a cadre of fully-functional stand-alone programs. Readers can use the examples as the basis and building blocks for their own software
