You may organize into collaboration teams of up to 3 current students. For each homework assignment, you can only be in one team and must list all team members on your homework submission, whether or not you specifically spoke with them. You may have different teams for different assignments.

Collaboration can only consist of discussions. You must write your solutions on your own. Sharing of solutions essentially as they are written in a LaTeX file, an email, a PDF, over Zoom, or elsewhere is not allowed. This includes submitting solutions that you obtain from the web or from people not enrolled in CIS 160. Penalties could include failing the course and/or being reported to the Office of Student Conduct.

The only materials you may reference when writing homework solutions are course materials (lecture notes, homework solutions, and recitation guides).

If you would like to use part of a solution from a problem presented in lecture, recitation, or past homework solutions you may do so with attribution; i .e., provided you add a comment in which you make clear you copied it from these sources.

Example of Allowed Collaboration

• Val lists Swap and Sampath as collaborators.
• Sampath lists Swap and Val as collaborators.
• Swap lists Val and Sampath as collaborators.

Example of NOT Allowed Collaboration

• Val lists Sanjeev and Sampath as collaborators.
• Sanjeev lists Sampath and Swap as collaborators.
• Sampath lists Swap and Val as collaborators.
• Swap lists Val and Sanjeev as collaborators.

This example is a violation of the policy since the size of the team is 4 (which is bigger than the maximum of 3 allowed). Sanjeev would have to list Val, which would give him 3 collaborators.

Example of NOT Allowed Collaboration

• Val lists Sanjeev as a collaborator.
• Sanjeev lists Val and Sampath as collaborators.
• Sampath lists Sanjeev as a collaborator.

This example is a violation of the policy since Val does not list Sampath. Even if Val and Sampath never directly spoke to each other, they are considered part of the same “team.”

Other examples of collaboration which are NOT permitted include:

• Discussing or solving problems with friends not enrolled in the course.
• Posting questions on the internet or searching for solutions on the internet.
• Borrowing a friend's solutions.
• Giving your solutions to a friend. This includes screen sharing documents.
