Use Canvas to upload your solutions to the assignments by the due date and time.
Submit the solution to each problem as a separate pdf file. You can typeset solutions on a computer or scan / photograph handwritten solutions. You are responsible for making sure that your solutions are readable. Typesetting makes that easier.
If you do not see CSE 311 in your Canvas account, please send an email to the cse311-staff@cs mailing list, and we will work it out with you.
The midterm exam will be held in class on Wednesday, November 07.
The midterm will cover everything up to the end of ordinary induction in Lecture 16 (but not strong induction). It will be closed book and closed notes. You will get lists of inference and equivalence rules on the exam.
To get an idea of the content and length of the exam, take a look at the following material:
There will be a review session on Sunday, November 04 at 15:00-17:00 in SAV 260.
The final exam will be held on Monday, December 10 at 14:30-16:20 and 16:30-18:20 in JHN 102.
In the case of a scheduling conflict, students may take the exam at either time but must email the staff (cse311-staff@cs) by Sunday, December 09 indicating when they will take the exam. Students must bring their UW ID and have it ready to be checked during the exam.
The final exam will cover the entire course, but it will emphasize the material not covered on the midterm. As a rough guide, you can expect two thirds of the final to cover the post midterm material.
To get an idea of the content and length of the exam, take a look at the following material:
There will be a review session on Sunday, December 09 at 15:00-17:00 in GWN 301.
Assignments must be turned in by the due date and time in order to contribute to your grade. Assignments will not be accepted late. In case of a severe emergency (e.g., hospitalization), contact the course staff (cse311-staff@cs). Unless otherwise noted, all assignments should be submitted via the course dropbox.
We will entertain questions about grades only for one week after they are posted in the course grade book. Questions about assignment grades should be written and submitted to the staff via email (cse311-staff@cs).
Clarity is important
One of the main goals (in fact, maybe the main goal) of CSE 311 is to be able to learn how to express ideas clearly using mathematical formalism.
Style is important
You may lose points for style. Your proofs and explanations should be clear, well-organized and as concise as possible. It is better to err on the side of including too many details. Unfortunately, a lot of this is subjective. Often, students think of proofs as merely either “right” or “wrong”. This would be true if they were expressed in every last detail in a formal logic but not at the level that you will need to write them here. Writing a proof is more like writing an essay. Along these lines, if you are not able to find a complete answer to a problem, you are better off explaining clearly what you’ve done rather than faking a proof.
A picture is not a proof
Pictures and short pieces of pseudo-code can be helpful, but they are not sufficient. Make sure to label everything. Define all the variables you use. Make sure you’ve explained everything clearly in English.
Review your proofs
Try rewriting your proofs. Writing out your answer fully on a piece of scratch paper before writing up the version to hand in really does make a difference. You are more likely to catch mistakes or exceptions, and your proof will be better organized.
Notation is key
Set up good notation. Many of the exercises are phrased almost entirely in English. It will be your job to rephrase them mathematically when necessary. Your proofs will usually begin with something like, “Let S be the set of students taking CSE 311.” Make sure that you’ve clearly defined any variable you use. Choosing good names for your variables is also important.
Homework should be written up individually. It is okay to discuss problems with a few other students, but you may not write up solutions in a group, and you may not record anything from your discussions.
If you have any doubt about whether your collaboration was appropriate, include a description of your collaboration with your homework submission.
You may not consult the Internet for problems or key-phrases. This includes Google, MathOverflow, reddit, and any other website. You may consult the internet for ideas, definitions, and understanding general concepts.
For additional information and a more detailed discussion, please refer to the Allen School Academic Misconduct Policy.
Homework assignments will often have extra credit problems. They will be scored separately from the regular problems, and they will have relatively little impact on course grades. The main incentive for doing the extra credit problems is for the challenge of doing the problems. Extra credit will be factored into the grade after course grades have already been calculated.
