In e-learning environment, Web-based testing system can help to evaluate learners learning status precisely. To meet the needs of multiple assessment criteria, a new test-sheet construction model was proposed. Based on the proposed model, a differential evolution algorithm with effective coding strategy was designed to generate high quality test-sheets for Web- based testing. In simulation experiments,...
The basic objective of generating test paper is to generate a high quality paper according to consumer's requirements. The existing algorithms are likely failed because of partially fulfilling constraint conditions of generating test paper. An improved particle swarm optimization is proposed for the problem. Natural number coding and subsection strategy are adopted in the new algorithm. The results...
