  • 设有一个SPJ数据库

    设有一个SPJ数据库,包括S、P、J、SPJ四个关系模式: S(SNO,SNAME,STATUS,CITY) P(PNO,PNAME,COLOR,WEIGHT) J(JNO,JNAME,CITY) SPJ(SNO,PNO,JNO,QTY) 供应商表S由供应商代码SNO、供应商姓名SNAME、供应商状态STATUS、供应商所在城市名CITY组成。 零件表P由零件代码PNO、零件名PNAME、颜色COLOR、重量WETGHT组成。 工程项目表J由工程项目代码JNO、工程项目名JNAME、工程项目所在城市名CITY组成。 供应情况表SPJ由供应商代码SNO、零件代码PNO、工程项目代码JNO、供应数据QTY组成,表示某供应商供应某种零件给某工程项目的数量为QTY。 上述四表中的具体数据可以参考教材30、31页。

    TFIND searches for one or more strings (boolean AND) in a text file. TFIND reports all lines where the string(s) were found (or NOT found by option). The search can be limited to a field in a fixed field (i.e. column oriented) list. An extended search mode is available, where only letters and digits are relevant. Other options: case sensitive search, alternative errorlevel with number of hits, header line with file name, LFN, custom prefix

  • 用分支限界法求解背包问题(0/1背包) 1.问题描述:已知有N个物品和一个可以容纳TOT重量的背包

    用分支限界法求解背包问题(0/1背包) 1.问题描述:已知有N个物品和一个可以容纳TOT重量的背包,每种物品I的重量为Weight,价值为Value。一个只能全放入或者不放入,求解如何放入物品,可以使背包里的物品的总价值最大。 2.设计思想与分析:对物品的选取与否构成一棵解树,左子树表示装入,右表示不装入,通过检索问题的解树得出最优解,并用结点上界杀死不符合要求的结点。

  • Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assum

    Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assuming BPSK. Brute force Monte Carlo approach is unsatisfactory (takes too long) to find the BER curve. The computation uses a quasi-analytic (QA) technique that relies on the estimation (approximate one) of the information-bits Weight Enumerating Function (WEF) using A simulation of the convolutional encoder. Once the WEF is estimated, the analytic formula for the BER is used.

    Swarm intelligence algorithms are based on natural behaviors. Particle swarm optimization (PSO) is a stochastic search and optimization tool. Changes in the PSO parameters, namely the inertia weight and the cognitive and social acceleration constants, affect the performance of the search process. This paper presents a novel method to dynamically change the values of these parameters during the search. Adaptive critic design (ACD) has been applied for dynamically changing the values of the PSO parameters.

    I built the Superlist control whilst developing an RSS reader called FeedGhost. Although there are plenty of commercial grouped list controls available I wanted to have total control over the code and of course its usability. Superlist supports drag drop column customisation, grouping as well as handling thousands of entries smoothly. It s also highly customisable if you want to change its look and feel. In this article I ll explain how to use and extend the control in a demo project. If you download the source, you can find demo project under the Tests/SuperListTest directory.
