Assignments must submitted as a PDF electronically through websubmit by 11:59PM on the day they are due. You may choose to hand-write your assignment and then scan it in before submitting, or you may choose to type up the assignment and then convert it to a PDF. You are encouraged to use LaTex; a template is posted above. No format other than PDF will be accepted. Please make sure the electronic version of your assignment is legible; illegible assignments will not be graded kindly.
Late lab submission. You start the semester with a credit of 3 late days. For the purpose of counting late days, a "day" is 24 hours starting at 11:59PM on the assignment's due date. Partial days are rounded up to the next full day. You are free to divide your late days among the take-home assignments (but not the final project) any way you want: submit three assignments 1 day late, submit one assignment 3 days late, etc. After your 3 days are used up, no late submissions will be accepted and you will automatically receive 0 points for each late assignment. Extra late days are not available.
Every submitted assignment MUST include the following information:
If any of this information is missing, 20% of the points for the assignment will automatically be deducted from your assignment.
- List of collaborators
- List of references used (online material, course nodes, textbooks, wikipedia, etc.)
- Number of late days used on this assignment
- Total number of late days used thus far in the entire semester
You are strongly encouraged to collaborate with one another in studying the course material. As long as it satisfies the following conditions, collaboration on the homework assignments is encouraged and will not reduce your grade:
It is your responsibility to know and understand the provisions of the CAS Academic Conduct Code.
- You may discuss ideas and approaches with other students in the class, but:
You must also acknowledge clearly in your solutions people with whom you discussed ideas, either for your written solutions or for your code.
- You (or your group) may not share actual code. In other words, the code you write must be entirely your own, which you must write and debug without looking at other people's code. Don't permit others to copy your code.
- You (or your group) must write up your solutions completely on your own, without looking at other people's write-ups.
- You may not work with people outside this class (but come and talk to us if you have a tutor), or get someone else to do it for you, etc.
- You are welcome to use any textbooks, online sources, blogs, research papers, Wikipedia, etc in your assignment, as long as these are properly cited in any submitted work. Failure to do this is plagiarism and is serious violation of the CAS Academic Conduct Code and basic scientific ethics, and will not be tolerated.
- You are not permitted to collaborate on exams.
