Abstract: . This paper extends existing work on the use of default information
to describe planning hierarchies in two ways. First, we present
a completeness result showing that all hierarchical planners can be described
using defaults. Second, we show that if the planning hierarchy is
situation-dependent, the default description is likely to have substantial
computational advantages over a more conventional approach.
1 Introduction
There are a variety of arguments for planners that work declaratively... (Update)
