Most practical work on AI planning systems during the last fifteen years has beenbased on hierarchical task network (HTN) decomposition, but until now, there has beenvery little analytical work on the properties of HTN planners. This paper describes howthe complexity of HTN planning varies with various conditions on the task networks,and how it compares to STRIPS-style planning.1 IntroductionIn AI planning research, planning practice (as embodied in implemented planning systems)tends to ...
