On the construction of a type of composite time integration methods

• General construction principles of a type of composite methods are proposed. • Several novel composite methods are constructed. • Accuracy is improved by increasing the number of sub-steps and time points used in BDF. • Similar composite methods can be developed via the same optimization rules....
