The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for the coding (compression) of natural video images. The new standard [1] will be known as H.264 and also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding: Context-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC). This document provides a short introduction to CABAC. Familiarity with the concept of Arithmetic Coding is assumed.

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.

Sherwood算法消除最壞實例，以達到對任何實例都能有好的性能的效果 文件： rd_list.c --> create a random sequence of n integers not equal to each other list.c --> create a descending sequence of n integers not equal to each other sherwood.c --> 就是該算法，靜態鏈表的長度默認設為1000，可在宏定義處修改 用法： gcc -o sherwood sherwood.c gcc -o rd_list rd_list.c gcc -o list list.c ./rd_list s.txt 1000 產生一個長度為1000的互不相等的隨機序列，保存在s.txt中 ./list s1.txt 1000 產生一個長度為1000的互不相等的降序序列，保存雜s1.txt中 ./sherwood s1.txt 運行算法，比較其中的4個算法的性能差異

兩種解決方案 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.)

壓縮解壓算法LZ77算法有許多派生算法(這里面包括 LZSS算法)。它們的算法原理上基本都相同，無論是哪種派生算法，LZ77算法總會包含一個動態窗口（Sliding Window）和一個預讀緩沖器（Read Ahead Buffer）。動態窗口是個歷史緩沖器，它被用來存放輸入流的前n個字節的有關信息。一個動態窗口的數據范圍可以從 0K 到 64K，而LZSS算法使用了一個4K的動態窗口。預讀緩沖器是與動態窗口相對應的，它被用來存放輸入流的前n個字節，預讀緩沖器的大小通常在0 – 258 之間。這個算法就是基于這些建立的。用下n個字節填充預讀緩存器（這里的n是預讀緩存器的大小）。在動態窗口中尋找與預讀緩沖器中的最匹配的數據，如果匹配的數據長度大于最小匹配長度 （通常取決于編碼器，以及動態窗口的大小，比如一個4K的動態窗口，它的最小匹配長度就是2），那么就輸出一對〈長度（length），距離（distance）〉數組。長度(length)是匹配的數據長度，而距離(distance)說明了在輸入流中向后多少字節這個匹配數據可以被找到。

The market for miniature computer programming is exploding. C++ Footprint and Performance Optimization supplies programmers the knowledge they need to write code for the increasing number of hand-held devices, wearable computers, and intelligent appliances. This book gives readers valuable knowledge and programming techniques that are not currently part of traditional programming training. In the world of C++ programming, all other things being equal, programs that are smaller and faster are better. C++ Footprint and Performance Optimization contains case studies and sample code to give readers concrete examples and proven solutions to problems that don t have cut and paste solutions.

To use the ATLTrace tool: Debug an MFC or ATL project select Start from the Debug menu. Select MFC/ATL Trace Tool in the Tools menu. Expand the tree control list in the Trace List window. Here you will see the running application, any modules within that application, and the trace categories for each module. Customize, for each process, module, and category, which information is displayed in the output window. The Trace level control in the Process group is related to the ATLTRACE2 level only those ATLTRACE2 messages with a level equal to or greater than the setting in the Trace level control will be displayed in the output window. Select Apply to put your settings into effect. You can save your settings, and load them the next time you debug the application use the Save and Load buttons.

1) Write a function reverse(A) which takes a matrix A of arbitrary dimensions as input and returns a matrix B consisting of the columns of A in reverse order. Thus for example, if A = 1 2 3 then B = 3 2 1 4 5 6 6 5 4 7 8 9 9 8 7 Write a main program to call reverse(A) for the matrix A = magic(5). Print to the screen both A and reverse(A). 2) Write a program which accepts an input k from the keyboard, and which prints out the smallest fibonacci number that is at least as large as k. The program should also print out its position in the fibonacci sequence. Here is a sample of input and output: Enter k>0: 100 144 is the smallest fibonacci number greater than or equal to 100. It is the 12th fibonacci number.
