設(shè)有一個SPJ數(shù)據(jù)庫，包括S、P、J、SPJ四個關(guān)系模式： S(SNO,SNAME,STATUS,CITY) P(PNO,PNAME,COLOR,WEIGHT) J(JNO,JNAME,CITY) SPJ(SNO,PNO,JNO,QTY) 供應商表S由供應商代碼SNO、供應商姓名SNAME、供應商狀態(tài)STATUS、供應商所在城市名CITY組成。 零件表P由零件代碼PNO、零件名PNAME、顏色COLOR、重量WETGHT組成。 工程項目表J由工程項目代碼JNO、工程項目名JNAME、工程項目所在城市名CITY組成。 供應情況表SPJ由供應商代碼SNO、零件代碼PNO、工程項目代碼JNO、供應數(shù)據(jù)QTY組成，表示某供應商供應某種零件給某工程項目的數(shù)量為QTY。 上述四表中的具體數(shù)據(jù)可以參考教材30、31頁。

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問題（0/1背包） 1.問題描述：已知有N個物品和一個可以容納TOT重量的背包，每種物品I的重量為Weight，價值為Value。一個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總價值最大。 2.設(shè)計思想與分析：對物品的選取與否構(gòu)成一棵解樹，左子樹表示裝入，右表示不裝入，通過檢索問題的解樹得出最優(yōu)解，并用結(jié)點上界殺死不符合要求的結(jié)點。

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.

法國cromda編寫的新版本MATRICE 2（矩陣和矢量運算單元）。 // ---------------------------------------------------------- // 12-01-02 : MODIFIED Matrice to Matrice2 (Delphi 6) // All routines now operate on rectangular matrix, except (InvMat and SysLin) // No more need to use the InitMat procedure (suppressed) : // - the routines detect automaticaly the dimensions of matrix and vector // - error code MatDimNul is generated if zero lines or column in matrix and vector (See DimensionMatrice and DimensionVecteur) // - error code MatMauvDim is generated if the dimensions of matrix/vector don t allow valid result // - // The result matrix is dimensioned automaticaly

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.
