Abstract


With the development of computer technology, the computer system has been applied to the education industry up Intelligent Grouping System is an important research direction, depends primarily on the Algorithmic a test paper system efficiency and generating test paper quality. A lot of randomness and uncertainty, traditional Algorithmic Exam changing requirements, and does not have the intelligence, can not capture the overall time complexity. And is often due to the constraints of local does not meet the test paper generation failed. Existing Algorithmic test paper low success rate, time-consuming, resulting papers difficult to meet the demand for the actual exam lack of genetic algorithm in the test paper problem Application. First, the basic theory and principles of Intelligent Test Paper Problem Description summarizes the design constraints in the test paper generation process, given the basic mathematical model of Test Paper Problem. And describes the characteristics of the basic idea of ??genetic algorithms and key issues, as well as the genetic algorithm. Secondly, on the basis of theoretical analysis, the use of the SQL database and C # language, developed in the Visual Studio 2008 environment for Intelligent Test System Based on Genetic Algorithm. System with user management, information management, papers parameter management, as well as Intelligent Test Paper. Design and implementation of the system, in accordance with the theory of software engineering, from the overall design goal of the system functional requirements and non-functional requirements in-depth analysis of the system requirements, system design principles and performance requirements. And the detailed design of the system is given on the basis of the analysis of the system requirements, including system structure, system parameters, database design, and design of genetic operators and Genetic Algorithm algorithm Test Paper code. In the design of the system architecture, the system in accordance with the user's visibility into the user interface layer, functional modules and data layers. In accordance with the three Paradigm requirements on the database design, and gives the ER diagram and table structure. Design genetic operators of the genetic algorithm with the specific circumstances of the Test Paper Problem combining real-coded method segmented to meet the characteristics of the test paper problem, and design the corresponding crossover and mutation operator. System design based on the use of modular programming ideas, systems development and coding system consists of a main form of user login module, the system module, the user management module, and information management module, papers parameter management module and Intelligent Test Paper module six modules. After the test of the system and data experiments show that, based on the genetic algorithm smart fast Algorithmic Test Paper, Test Paper quality is better, the actual test paper generation needs to meet the test paper to solve the problems, and achieved good results, with better practicability.
