Although most people believe that planners that delay step-ordering decisions as long as possible are more efficient than those that manipulate totally ordered sequences of actions, this intuition...

Use of Lexical Conceptual Structure for Intelligent Tutoring (1993)

Most practical work on AI planning systems during the last fteen years has been based on hierarchical task network (HTN) decomposition, but until now, there has been very little analytical work on...

: We describe the use of an LCS-based semantics for question-answering exercises in foreign language training. We start by reviewing the LCS model and show how this representation can be used to...

Merging Separately Generated Plans with Restricted Interactions (1992)

Qiang Yang, Dana S. Nau, James Hendler

Generating action sequences to achieve a set of goals is a computationally difficult task. When multiple goals are present, the problem is even worse. Although many solutions to this problem have...
