About CS3000

This is an introductory undergraduate course in algorithms. Every computer program can be viewed as an implementation of an algorithm for solving a particular computational problem. The focus of this course is on learning algorithm design techniques for solving the underlying computational problems. We will also look at how algorithms translate to programs, but our emphasis will be on the algorithm design and analysis. In this class, we will:

• Work on a range of computational problems that arise in diverse applications
• Learn how to formulate problems precisely from somewhat informal descriptions
• Learn algorithmic design techniques used to solve the problems
• Learn proof techniques critical for reasoning about algorithms
• Learn analysis techniques critical to determine the efficiency of algorithms

Lecture Schedule

CS3000 lectures introduce key concepts and dive into examples and applications. Lectures are in-person and attendance is expected. We don't want or expect anyone to come to class when they're sick, though, so we'll post notes after class every day, which you can use to catch up on any missed material.

CS3001 recitations will have an assigned problem set that will be graded based on effort and completeness. Recitations are in-person and attendance is expected. Although two meetings are on the official schedule, attendance is expected only at the Tuesday recitation. The Thursday recitation will be used for extra office hours and to go over recent homework solutions.

Piazza is a great place to ask follow-up questions after lecture or when you’re working on homework. You can also ask lecture-related questions directly to Prof. Strange so I can wrap them into the next lecture if appropriate. Please use this form to do so: https://forms.gle/JLKYYsnsskjaTCiD8

Teaching Assistants & Office Hours

TA office hours begin Tuesday, May 9th. There are no office hours on univeresity holidays.

TA office hours will be held in person and online (on the Khoury Office Hours app). The different locations will be indicated on the OH calendar below.

For online office hours, we will be using the queuing system in the Khoury Office Hours app. Have a question ready and add yourself to the queue. When a TA is available, they’ll call you on Teams. To make this all work, you’ll need:

• Microsoft Teams app (better than using it in a browser): https://www.microsoft.com/en-us/microsoft-teams/download-app
• A Khoury account (separate from your Northeastern Husky account): https://my.khoury.northeastern.edu/account/apply
• Access to the Office Hours app. Login from the admin portal (look for “Office Hours Login” on the left side of your screen): https://admin.khoury.northeastern.edu/
• To read the manual https://info.khouryofficehours.com/c78a201f396642e3b3f7215a1a3283a6 and watch this helpful demo: https://www.youtube.com/watch?v=9h8ZpSrKErs.

For in-person office hours, please go to the room listed and write your name at the bottom of the list on the whiteboard. A TA will call your name when it’s your turn, so please keep an ear out!

For both in-person and online, it’ll be important that you come to office hours having already made an attempt on the homework. TAs will be happy to help guide you on concepts and provide clarification on concepts. They cannot provide you with answers to problems.
