Representation and Reasoning for Pragmatic Navigation

Susan L. Epstein

This paper focuses upon features of two-dimensional space that facilitate and/or obstruct travel through it. Three kinds of facilitators and four kinds of obstructers ate identified. For each one, learning algorithms and navigational applications ate proposed. The program described here simulates a robot that learns such features as it encounters them, and then applies them to subsequent travel decisions. The resulting system travels pragmatically through a variety of twodimensional worlds.
