I've reorganized the directories for homeworks.
The links from the schedule now point to the new directory but if you have a direct link to the Homework #1 assignment you'll have to change it from
http://www.cse.ohio-state.edu/~parent/classes/541/Assignments/hw1.html
to
http://www.cse.ohio-state.edu/~parent/classes/541/Assignments/HW1/hw1.html
