The ideas must be your own, but you can get help with the expression of those ideas. Such helpers must be acknowledged . Likewise, you are free to read other students' papers and comment on them. If you get a good idea from another student's paper, you must acknowledge that student as the source of the idea, just as you would do if you found a good idea in a published paper. Library sources must be acknowledged when you submit your homework, even if you find little or nothing useful .
Some students rely heavily on the library.
Although this is permitted within the letter of the rules, I discourage it. While library skills are important in our profession, the homework in this course is designed to develop other skills that are even more important. This is ten minutes after midnight . If you plan on submitting your work at midnight, you will have ten minutes for last-minute changes. Late policy is roughly consistent with other CS classes.
