Abstract


With the rapid development of computer technology, and how to effectively use the computer to reduce the workload of teachers, computer-related questions from existing test database, automatic composition, the formation of a professional teacher standards papers is a very meaningful the subject in the past 20 years has generated a lot of theoretical knowledge, and many mature knowledge of the application to the computer test paper generation technology, the computer test paper generation technology rapid development, but due to a computer group The constraints of the volume is a combination of a multi-constraint solving problem. Computer Test Paper technology has achieved good results, but the good or bad evaluation of the performance of the algorithm with the test paper intelligence is still a very important significance of the application subject. First, the history of the development of the technology of the computer Test Paper, Test Paper introduced relatively common technology, and analysis of the shortcomings common Algorithmic On this basis, the existence of intelligent test paper several problems, the enormity of the task of Intelligent Test Paper Technology. Second, the analysis of the mathematical model of Test Paper Problem, Algorithmic a relatively standardized Test Paper Solution Procedure, and on this basis according to the paper - making strategy used by the algorithm currently used Algorithmic comprehensive classification and the types of Algorithmic the detailed description, focus segment genetic algorithm-based Test Paper Strategies conducted a more detailed introduction to the theory and achieve technically. Then, the characteristics of problem solving for the Algorithmic the multi constraints, reducing the Test Paper the number of invalid papers in the process of generating test paper, in order to reduce system overhead, introduced the concept of backtracking consideration proposed algorithm based on minimum retrospective consideration Intelligent Test Paper by preferentially selecting a unit having the smallest backtracking consideration questions, to the maximum possible to reduce the overhead incurred by the invalid papers in Test Paper process, thereby ensuring the effectiveness of the algorithm. Theoretical analysis shows that the new algorithm has better performance. Minimum backtracking with a piece of thinking at the same time, given the Algorithmic Algorithmic single set of papers with multiple sets of papers. Finally, for smart Algorithmic design a simple application of the system, analysis of the overall design of the system function structure analysis, as well as the related database information.
