Research On Composition Papers System Based On Genetic Algorithms

With the development of Internet and Computer Science,Internet is used in more and more field including education.There are lots of so called distance learning system. Online learning plays an important role, so it is necessary to develop an online exercise system to keep up with the developing steps of distance learning systems.With the development of network technology, the methods of test changes greatly. The computerized test system can shorten the circle of exam workflow, lessen the repeating work of teachers, and improve the efficiency. The intelligent paper forming function it supports can improve the quality of test papers and increase the objectivity of test. At the same time, the web-based test can be taken at any time and any place. The form of test becomes more flexible and free.The essential of the computerize intelligent paper forming is to manage a optimization test paper that satisfies the parameters which the user inputs, so that the paper forming problem is a classical Constraint Satisfaction Problem (CSP). The genetic Algorithm (GA) is a new kind of whole optimization algorithm, and it uses the biologic genetics'point of view to raise the individual's adaptability by the natural selection, heredity, mutation. And it is in favor of solving the CSP for its whole searching, random city, well coding method and high parallel, so the...
