Homework Assignments

The programming and written assignments count for half of your final grade. Much of what you learn in this course will be through completing these assignments. Your final homework grade is the average of your grades on the seven assignments.

Handout and Handin

Assignments will be made available on this Web page, and solutions are to be submitted via autolab. To submit a homework to autolab, run make in the root directory of the assignment. This will generate handin.tar which may then be uploaded to autolab. After submitting please check to make sure that the 1 point problem check is 1.0, this means that all of the necessary files were present and that your code compiled. If it is 0.0, your submission is incomplete. You may make as many submissions as you like before the due date, only the latest will be graded.

Remember that written assignments must be submitted to Gradescope (not Autolab).

In general, for programming assignments we ask that you submit your code and a brief README detailing anything you think we need to know to understand your submission. The written assignments are to be typeset in LaTeX and submitted in PDF format. The tex directory contains some examples and macros for typesetting PFPL material.

Late Policy

Every student has up to 3 late days for use on any assignment throughout the semester, but no homework may be more than two days late. For example, a student may hand in Assignment 1 one day late and Assignment 4 two days late, but then all remaining assignments must be handed in by the deadline. By one day late we mean 24 hours late.

Late homework should be submitted as usual, by autolab. Autolab will automatically mark late submissions by the appropriate number of late days. This will be used to determine whether or not a student has used a late day.

No homework assignment will be accepted more than two days after the due date. Once you used your budget of three late days for the semester, each late day will be assessed a 25% on your grade for that assignment. So, if you are two days late and over budget, you can earn at most 50% credit for an assignment.

Extra Credit

Some assignments will have extra credit questions. The intent is for such questions to be interesting, although some may be very hard. Partial answers and half-baked ideas are welcome and will receive some credit as long as it is clear you have seriously considered the question. See the home page for how extra credit will count towards your grade.
