Recognizing Plan/Goal Abandonment

Contents

This paper describes ongoing efforts to extend our work (G&G) on the Probabilistic Hostile Agent Task Tracker (PHATT) to handle the problem of goal abandonment. As such, we will be discussing both probabilistic intent inference and the PHATT system and assume the reader is familiar with these areas. We refer the interested reader to the complete paper and to our earlier papers for more discussion of these issues.1
