Abstract

With the rapid development of Internet in the international, more and more web-based applications were increasingly subject to people's attention in recent years, and the modern distance education tremendous development. The web-based examination system is emerged in such a situation. Although the traditional form of examination is also very common, with the expansion and universality of distance learning, the online examination system come into being as a subsystem of distance learning system.

Automatic Test Paper is a crucial part in the examination system. With the rapid development of artificial intelligence, this issue a growing number of scientists concerned. Automatic Test Paper is the real follow a strategy of topics, and select a group of questions from the questions, makes them all the properties are within a certain range by volume to meet the expectations index. The core of the problem is multi-target strategy of choice. The design of database is also a very important part in the examination system, and the design of database is good or bad will directly affect the effectiveness of automatic Test Paper.

This paper designs and implements an on-line examination system, and its functions include on-line examinations, test management and maintenance, automatic Test Paper, Grade examination papers and grade point, seeing results and information management features such as students etc. It focuses on the automatic Test Paper algorithm and the database design project, and gives the Test Paper algorithm and the database design project of on-line examination system integrating the characteristics of on-line examination system.

Test Paper algorithm is the focus of the research, and in a large number of domestic and international literature on the basis of, this paper use a genetic algorithm as a intelligence and optimization Test Paper to solve the problem of Test Paper. Algorithm is carried on the detailed design and analysis in the text,
