All, Please remember that there is also a HW#4: http://www.cs.stevens.edu/~jschauma/615A/s11-hw4.html This assignment is of much more importance than the silly HW#5 exercise. Finally, I've added a section on gaining extra credit to the website: http://www.cs.stevens.edu/~jschauma/615A/extra-credit.html All of those "assignments" are still open. -Jan
