Discussions on homework and computer assignments are encouraged: you can learn a lot from working with a group. This means that you are permitted to discuss homework problems and computer assignments with classmates, and are permitted to seek help from other students if you run into difficulties. However, material submitted for grading should represent independent work of its author. Any work done in collaboration should be clearly marked as such. It is not acceptable to copy the work of other students, and it is not acceptable for two students to submit identical copies of any part of an assignment.
