Your grade will have 3 components:
- Problem sets (35%)
- Project (35%)
- Final exam (30%)
- The problem sets will be available on this web page about once every two weeks.
- The problem sets will be turned in on Gradescope.
- For the problem sets, if you use any external material to solve it (other than the lectures and any referenced sources), cite the source and indicate what you took from it.
- You may discuss problem sets with other students, but you must understand and write up your solution by yourself. If you do collaborate, indicate who you talked to on your assignment.
- Problem sets may be turned in up to 3 days late without penalty. If you need an extension beyond this, let me know; however, remember the reason needs to be good enough to justify a longer than 3 day extension.
- Performed in groups of 1-5 people (larger groups will need more content covered).
- Should present original research or the main results from 1-5 research papers, depending on length of the papers, overlap between them, and group size.
- Each group will turn in a written report (length 10-30 pages, depending on group size and scope of the project) and give a brief presentation in the last week of class.
- The writeup should contain a brief summary of the contributions of each member of the group.
- Most likely take-home.
- More information to be announced closer to the exam.
