As with all other classes at Cornell, you are expected to maintain a high level of ethical standards and integrity in this course. This means that all work you submit must be the result of your own individual effort. You may discuss homework problems with other students in the class, but you may not collaborate on the actual writing of the problem sets or development of solutions. Under no circumstances would it be acceptable for two or more students to turn in substantially similar answers to a homework problem, or to have possession of each others' homeworks. Everyone with whom you discussed the homework set must be cited on the submitted homeworks. No part of the homework may be copied from or be based on solution sets on the web - also keep in mind that the solution sets on the web are often incomplete and incorrect.
The same standards apply for group projects, though at the group level. Group members are expected to turn in the result of their collaborative work with other members of the same group. No group should at any time be in possession of another group's solution, or copy another group's solution. It is your responsibility to protect your work from unauthorized access.
Any violations of the academic integrity code will be penalized according to the Cornell Academic Integrity Policy, and may result in failure in the course, suspension, or expulsion from the university.
