The Design And Implementation Of Online Exam System Based On Genetic Algorithm

By contrast,online exam mode is more convenient than traditional exam,which also has improve the efficiency.In this paper,online exam system based on genetic algorithm has been designed and implemented.From this point,the ASP technology has been adopted in the paper,and the design and realization of the online exam system based on campus network has been researched.The achievements have been reached:1)The principle of assembling paper has been studied.It has established the mathematical model B(n,p)based on discrete random variable to reflect distribution of difficulty.The multiple target mathematical models has been established that involves varies score and chapter.2)The global restriction assured the finiteness and scientificalness of abstraction which consist of 4 vectors.With the weight coefficient,the mathematical model was converted to linear model so that it is easy to solve the model with the GA algorithm.Algorithm optimization of the elite preservation strategy has been used to shorten the convergence time,and the Genetic Algorithms was used to solve the mathematical model.3)The online exam system based on B/S mode has been developed by use of Visual Studio.Meanwhile,the security policy of the online exam system has been promoted in three ways such as Network,database,ASP application.Based on classical test theory,the multi-target optimization mathematical model has been developed which involves degree of difficulty and discrimination index.At last,Database test is used to check the system in order to assure the serviceability and robustness of the system.
