Course Timetabling Problem during COVID-19 : An Optimal Model Based on the Comparative Advantage of Online/Offline Education

COVID-19 has profoundly changed the way that we study and work. For students, especially primary and middle school students, online education has become a solution to learning problems. However, online and offline education have their own characteristics and different learning efficiencies in different disciplines, which in turn will bring different learning effects. Therefore, based on the learning styles and types of knowledge, we establish an optimization model by weighing the comparative advantages of online and offline learning, so as to make the best learning effect for students. Then, a course timetabling algorithm proposed verifies its feasibility through examples
