Based On Genetic Algorithm Of Automatic Generation Of System Design And Implementation

With the development of computer technology, the existing teaching content, teaching methods and teaching methods the face of unprecedented challenges. Computer-aided examination system is becoming one of the people's research. Computer-aided examination questions through the library system automatically examination papers, the traditional examination of a number of links reduced to 1-2 links, saving a lot of manpower, material, but also significantly improve the test scores of objectivity and impartiality.This article first introduced the history of computer test paper generation technique development. On the basis of analyzing a large quantities of references home and abroad, this thesis has made a survey on the automatic generating test paper algorithm. Then we analyzed the shortcomings of the techniques.Secondly, this thesis summarizes the research background of auto-generating test paper systemically, detailed analyses of evaluating indicators and their functions, relationships of some important indicators; a test paper generation mode was set up with the distributions of the evaluating indicators. And we analyze all kinds of constraint conditions during the process of auto-generating test paper farther. We establish a model of generating test paper problem and simplify it. We obtain a standard process of test paper generation by analyzing mathematical models in test paper generation problem. Based on that we study according to the generation arithmetic which are in common use now. We give our best efforts on a detailed introduction to the generation strategy based on genetic algorithm, both theoretically and practically.Adaptive genetic algorithm optimization and its good intelligent search technology, has been widely used. Many scholars to retain the best genetic algorithm convergence rate has been discussed. Through the use of theory and fact, found in the genetic algorithm optimization and convergence are very effective.Thirdly, aiming at the characteristic of automatic generating test paper system, this thesis makes use of the national code which is used in the genetic algorithm in order to decrease space of chromosomes. This simplify the problem of drawing the results.Finally, the engineering implement problems of the automatic generating test paper system based on genetic algorithms are discussed in detail, and the system has been achieved using VB. In this thesis, some codes are provided.
