Listen to this interview of Istvan David, Assistant Professor of Computer Science, Department of Computing and Software, Faculty of Engineering, McMaster University, Canada; and, Houari Sahraoui, Full Professor, Department of Computer Science and Operations Research, University of Montreal, Canada.
