The design of the strategy of test paper auto-generating based on classification and synchronous optimization function

摘要

The system of intellectual test paper generating based on web technology has become an important method in computer aided instruction (CAI). The strategy of test paper generating is the key to the system. Based on the study of a test paper generating problem, a function method of classification of questions and synchronous optimization for multi-constraint conditions was proposed. Concrete implementation of the function algorithm was analyzed. Experiments show that the strategy for selecting questions automatically according to constraint conditions of quantity, knowledge point and difficulty works well. The strategy is simple, efficient, stable and practical.
