Research and design on a multi-target test paper-generating system and the core algorithms

A multi-objective test paper-generating system and the core algorithms—selecting items algorithm and an algorithm of setting score,are studied in this paper.The multi-target programming theory is used to model the test paper-generating algorithm.The strategy of selecting items and function modules are designed and implemented.The dynamic setting score algorithm is designed and implemented.Through comprehensive analysis,the relationship between the difficulty and test time is built and the test paper-generating system is implemented.Finally,the experiments show that the algorithm can get satisfied results under different requirements.The difficulty,score setting,time setting and amount of items can all be distributed reasonably in this system.
