Design And Implementation Of Intelligent Paper Organization Examination System Based On Genetic Algorithm

With the mutual integration of computer technology and education,which has promoted the transformation of education and teaching networks,the online examination model has gradually become an important means of new education measurement.The online examination through the Internet can save the workforce and material resources in the examination process.The storage and transmission of various test information,the current online test method has been used by more and more tests.The core of the online examination system is the function of intelligent test papers.The essence of the test papers is the optimal solution of multi-objective constraint problems.Using an algorithm to calculate and select the test questions that meet the conditions,then the system automatically combines them into a test paper.Ensure the quality of the test papers,make the test papers more objective and scientific,and achieve fairness and justice in the test.At present,the online examination system has achieved the functions of candidates' answering questions,viewing scores,and system test papers,but there are poor test paper performance,poor test paper quality,uncontrollable test paper difficulty,random test questions,and insufficient test auxiliary functions Perfect,high requirements on hardware resources,weak scalability,and maintainability.Because of the above problems,this paper analyzes the relevant theories of test paper formation,determines the use of genetic algorithms as intelligent test paper formation algorithms,and designs and improves the genetic operation process of test paper formations.At the same time,it conducts an in-depth analysis of system functions and frame technology and establishes.The functional framework of the system is determined by adopting the SSM(Spring,SpringMVC,MyBatis)framework for system construction and using MySQL to store and manage data.Finally,the intelligent test paper test system is implemented,and theimplementation process of each functional module is described in detail.The main work and innovations of this article are as follows:(1)In terms of system test paper composition,this article sets specific constraints such as the difficulty of the exam,knowledge coverage,total test scores,and some of test questions.It optimizes and extracts test questions from the test library to form test papers,improving the intelligence and Improve the quality of test papers and make them better meet the test requirements.(2)Optimize the operation process of genetic algorithms in test papers,analyze the relevant theories of test papers,map the constraints of test questions to the expression space of genetic algorithms,design a real number coding strategy based on the question type and generate an initial population according to the question type,and design the fitness Functions,improvement of genetic operators.The use of elite retention strategies is proposed to make the test results more objective and scientific.(3)Establish a complete system functional framework,conduct detailed requirements analysis and design of each functional module of the system,use UML modeling language to display the core modules in the form of class diagrams,timing diagrams,etc.,and design the system database,while using the MySQL database Store and manage data to improve the usability and functional integrity of the system.(4)Analyze the role of Spring,SpringMVC,and MyBatis frameworks in system development,and apply them to the system,integrate various functional modules,improve the maintainability and stability of the system,the system meets the purpose and requirements of system design and realizes the teacher Management function.In the end,this article realized a set of online management system for teacher management functions,intelligent test papers,and digital management of the test bank.
