[Delphi/CppBuilder] bbjm DL : 0: 利用分治策略,提出一种基于SIMD共享存储计算机模型的并行背包问题求解算法.算法允许使用O(2n/4)1− ε个并行处理机单元,0≤≤ε1,O(2n/2)个存储单元,在O(2n/4(2n/4)ε)时间内求解n维背包问题,算法的成本为O(2n/2).将提出的算法与已有文献结论进行对比表明,该算法改进了已有文献的相应结果,是求解背包问题的成本最优并行算法.同时还指出了相关文献主要结论的错误.-The use of sub-rule strategy, a shared memory based on the SIMD model of parallel computer algorithm knapsack problem. Algorithm allows the use of O (2n/4) 1-ε of parallel processor units, 0 ≤ ≤ ε1, O (2n/2 ) a memory cell, in the O (2n/4 (2n/4) ε) time for solving n-dimensional knapsack problem, algorithm of cost O (2n/2). the proposed algorithm with the existing literature shows that the conclusions, The algorithm improves the corresponding results of the literature is the cost of solving the knapsack problem the optimal parallel algorithm. At the same time, also pointed out that the main conclusions of the relevant literature mistake.

[Delphi/CppBuilder] huffmanTree DL : 0: 利用哈夫曼编码进行通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求发送端通过一个编码系统对数据进行编码，在接受端将传来的数据进行译码。试为这样的信息收发站写一个哈夫曼编码/译码系统。-Huffman coding communication can greatly improve the channel utilization, shorten the time of transmission of information, reduce the transmission cost. However, this requires the transmitting side through a coding system to encode the data, and decodes the data at the receiving end will be coming. Test for such information transceiver station to write a Huffman coding/decoding system.

[Delphi/CppBuilder] Challenges-in-Data-Crowdsourcing DL : 0: This because IP addresses are location-dependent and change with host mobility and VM migration. Network configurations and policies, such as access control policies, specified by IP addresses require frequent updates that impose a large administrative burden. As an example, Google’s globally distributed scales up to millions of machines across hundreds of data centers [10] that are interconnected in layer 3. Using a scalable layer-2 networking technology, management complexity and cost of such huge networks could be significantly reduced.-This is because IP addresses are location-dependent and change with host mobility and VM migration.
