Professor George is interested in large scale scientific computation generally, but mainly in problems associated with solving very large sparse systems of equations. A sparse system of equations is one in which most of the coefficients in the equations are zero. This is a natural consequence of the fact that models for physical systems usually involve direct relations only among quantities that are “close” to each other. For example, the stresses at joints at opposite edges of a bridge or an airplane are not directly related, but only indirectly related through relationships among joints that are directly connected by a beam or strut. Thus, the vast majority of systems of equations that arise in science and engineering are sparse. Moreover, solving these systems represents a major component of the total cost of the design and analysis of the structure. Professor George's interests are in the development, analysis and implementation of efficient methods for solving such systems.
He and his students have developed a software package called SPARSPAK, which is widely distributed under license by the University of Waterloo.
