Problems solved by technology

[0003] Existing examination methods generally use traditional optimization algorithms and traditional search algorithms, and traditional optimization algorithms iteratively seek the optimal solution from a single initial value, so it is easy to enter the local optimal solution by mistake; and the tradit

Embodiment

[0012] Such as figure 1 Shown, the present invention utilizes genetic algorithm to carry out the method for automatically forming papers for the examination questions in the question bank, and it comprises the following steps:

[0013] 1) Carry out real number encoding for all test question numbers in the question bank;

[0014] Because the solution of the genetic algorithm is to map the solution space of the problem into a set of code strings, that is, the coding problem of the test questions in the question bank. In the traditional genetic algorithm, binary coding is used, and when binary coding is used, each question in the question bank must appear in this binary bit string, 1 means that the question is selected, and 0 means that the question is not selected, resulting in multiple The binary bit string of the selected / unselected test paper composed of four test questions is long, and when performing crossover and mutation genetic operator operations, the number of questio...

Abstract

The invention relates to a method for automatically forming test papers in a test bank by using a genetic algorithm. It adopts real number codes for the test questions in the test bank, which can overcome the shortcomings of using binary codes in the past that the search space is too large and the code length is too long. The decoding time of the test papers to be assembled improves the speed of obtaining the final test papers. In addition, the present invention generates the initial population of the test papers to be grouped by randomly generating the initial population according to the total number of questions, the proportion of questions, and the total score of the test papers to be grouped, which can speed up the convergence of the genetic algorithm and reduce the number of iterations, thereby reducing Formation time of the test paper. Therefore, the present invention can be widely used in the field of automatic paper formation.

Description

technical field [0001] The invention relates to a method for forming papers, in particular to a method for automatically forming papers for test questions in a question bank by using a genetic algorithm. Background technique [0002] At present, the paperwork of various written test papers is basically done manually. Usually, when a formal examination is released, the corresponding examination organization invites experts in various fields to conduct analysis based on the examination population and examination objectives, and to formulate questions in a closed and concentrated manner. Then, according to the actual needs, select the chapters, knowledge points, and question types of the required test papers, and manually complete the whole process of test paper composition, resulting in a lot of resource investment, high cost, heavy workload, incomplete coverage of knowledge points, and failure to produce test papers. The volume takes a long time and so on. Therefore, the au...
