摘要
The general concept of a class of alternating difference block methods and their difference graphs are introduced.The methods are unconditionally stable,and according to the difference graphs the design of parallel algorithms and programs of the methods are flexible and easy.The traditional alternating explicit-implicit method,the ADI method,the AGE method,the Block ADI method and the ABE-I method are all the special cases of this class of methods.Their difference graphs are presented.
