# CSE 312: Homework

## Spring 2013

#### General Instructions

Bundles: The problems in each homework assignment will be divided into 2 groups (one per TA). You will turn in 2 corresponding bundles. Each bundle should be stapled separately, with your name on each. We don't supply the stapler.

When asked for a short answer (such as a single number), also
*show and explain your work* briefly. If your answer is too
large to evaluate easily, you can leave it in terms of factorials,
combinations, etc., for instance 26^{7} or 26!/7! or 26
(^{26}_{7}).

#### Policy on Collaboration

You are to complete homework assignments individually. You may discuss the assignment in general terms with other students, including a discussion of how to approach the problem, but the solution you write must be your own. The intent is to allow you to have helpful brainstorming sessions when you are stuck, but this help should be limited and should never involve details of how to solve the problem. A good rule of thumb is that you should never carry away anything written from one of these brainstorming sessions: if you cannot recreate the solution on your own later, then you do not truly understand the solution and you have received too much help from your collaborator.You must abide by the following rules:

- You may not work as a partner with another student on an assignment, unless explicitly allowed by the assignment specification.
- You may not show another student your solution to an assignment.
- You may not have another person (current student, former student, tutor, friend, anyone) "walk you through" how to solve an assignment.
- You may not look at other people's written solutions to problems, not in your friends' notes, not in the dorm files, and not on the internet.
