Embodiment Construction

[0026] The technical solution adopted by the patent for the present invention to solve its technical problems is: figure 1 , figure 2 As shown, the random permutation algorithm, constraint strategy, genetic algorithm and improved genetic algorithm are used to generate multiple sets of test papers;

[0027] 1. Mathematical model of intelligent paper composition

[0028] (1) Determine the relevant attributes of the test questions

[0029] For the parameters of the intelligent test questions, various attributes of the test questions are listed in some documents. For example, for a question, there are: chapters, question types, details, levels, requirements, question types, difficulty coefficients, difficulty levels, and chapter scores. The remaining attributes, according to our actual experience in the process of forming test papers: too many constraints increase the difficulty of the actual test test and reduce the efficiency, which makes the genetic algorithm fall into a loc...

Abstract

An anti-cheating examination system based on encrypted identification codes belongs to the technical field of preventing reference personnel from cheating in large-scale written examinations. The invention solves the problem in the prior art that it is impossible to completely cut off the cheating of reference personnel by using high technology. That is, a system and its implementation method for preventing cheating in exams by using computer software. The system is divided into two parts, the center end and the client end. The system software part includes six major subsystems, namely a test bank management subsystem, b test question element random arrangement test paper subsystem, c intelligent test test set subsystem, and encryption identification code Generation subsystem, e-marking and scoring management subsystem and f-examination analysis subsystem. At the same time, the system provides random arrangement of the test items according to the random arrangement algorithm, and according to a certain constraint strategy, thereby automatically generating test papers. After the test is over, the system provides automatic marking and test paper analysis functions. The anti-cheating method is simple and practical, the operation cost is low, and it is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of a device for preventing referees from cheating in large-scale written examinations and its implementation method, and in particular relates to a computer system for preventing cheating and its implementation method. Background technique [0002] China is a country with a long tradition of examinations, and cheating in examinations is not uncommon. Since 2001, using high-tech electronic means to cheat has become an important method for candidates to cope with exams, and even cheating has gradually developed into an industry. At present, the types of examination papers and answer sheets are usually divided into two types. The AB papers are distinguished. Candidates can know the type of examination papers in their hands, and then let the personnel waiting outside the examination room use high-tech communication means to transfer the corresponding types of examination papers The answers are sent to the test ...
