Course Information
Goals and topics
The goal of the course is to familiarize students with the dominant paradigms for mathematically rigorous design and analysis of classical, sequential algorithms. After taking this course, students will be prepared: to interface with and design sophisticated modern algorithms in software engineering; go on to (self-)study advanced or specialized topics in algorithms; study related topics such as machine learning.
- Module 1: Combinatorial and Graph Algorithms
- Paths and graph search
- Dynamic programming
- Flows and cuts
- Matchings
- Module 2: Approximation, Online, and Randomized Algorithms
- Approximation algs, e.g. greedy matching
- Online algs, e.g. ski rental
- Randomized (and approximation) algs, e.g. max-cut
- Settings combining all three features
- Data structures, e.g. hash tables
- Module 3: Continuous, Linear, and Convex Methods
- Linear algebra and graphs; random walks
- Dimensionality reduction
- Online no-regret learning; zero-sum games
- Linear programming applications
Prerequisites
This course will be theoretical, mathematically rigorous, and proof-based. We will assume familiarity with undergraduate algorithms (such as CSCI 3104), data structures (such as CSCI 2270), discrete mathematics (such as CSCI 2824), linear algebra, and calculus. Students may also be expected to implement small programs in a programming language of their choice.
Students should already have learned and reviewed the following material. Students lacking these prerequisites are strongly encouraged to take CSCI 3104 first.
- Big-O, Big-Theta, Big-Omega notation and their mathematical meanings.
- Basic data structures, heaps, binary search trees.
- Algorithm design approaches: divide-and-conquer (analysis using recurrences), greedy algorithms, dynamic programming.
- Algorithms for basic search and sorting (bubblesort, mergesort, quicksort, etc).
- Basic graph algorithms: breadth- and depth-first search, shortest paths, spanning trees.
- Definitions of P and NP complexity classes, the notion of NP-hardness.
When you have questions
- Course logistics: (1) read this page; (2) post on Zulip; (3) email TA or instructor.
- Assignments and course material: (1) re-read course notes; (2) consider reading linked resources; (3) post on Zulip and discuss with fellow students; (4) attend office hours.
- Confidential or non-course-related: email instructor.
Assignments and Evaluation
- Readings and videos: Prior to each class we will typically assign a video and a reading. Students should expect to spend an hour with this material before each class. This will allow us to use class time to solve problems (including homework problems).
- Homework (60% of grade): Assignments will usually be due every week and turned in using Gradescope.
- Midterm exam (15% of grade), details to be announced on course homepage.
- Final exam (20% of grade), details to be announced on course homepage.
- Participation (5% of grade), by asking and answering questions on Zulip.
The final score will be calculated by a weighted average of the grades in each component, subject to Drop policies below. The instructor does not have discretion over the student's final score. Course letter grades will be assigned based on final scores using grade cutoffs.
CSCI 5454 Policies and Logistics
Remote and Asynchronous Students
Students, including those enrolled in the remote (virtual) section, are strongly encouraged to attend synchronously unless they have another class or work conflict. Students who have a conflict are asked to notify the instructor.
Homework Policy (Drop 2 Rule)
Each student's two lowest homework grades will be dropped and the homework component of their course grade will be calculated by averaging scores on remaining assignments.
Because of this, we will not accept late homework for any reason (it will be dropped instead).
This allows students two emergency or exceptional scenarios during the semester that prevent them from turning in homeworks, as these two zeros will not affect their final grade. It also allows our staff to post solutions and return homeworks to students as quickly as possible, which improves the feedback cycle and learning process.
If a student faces an on-going exceptional situation that is likely to prevent on-time submission of three or more homeworks, they should notify the instructor as soon as possible.
Collaboration and Homework Policy
- Students are encouraged to work together to understand course material, including homework material.
- Students must write their own homework solutions themselves in their own words.
- Each homework must list the people the student collaborated with and external resources consulted (people not affiliated with the course or materials not mentioned or linked on the course site).
- Students may consult external resources for general understanding of material covered in class (e.g. "how does topological sort work?") and are encouraged to share useful resources with others on Zulip.
- Students may not use external resources to find solutions to specific homework problems.
- Students may NOT collaborate on exams nor use external resources of any kind.
- If this policy is unclear or you have any questions, contact the instructors e.g. by posting on Zulip.
Regrade Policy
Grading will assess the submission as written according to a rubric that is equally applied to all students and cannot be changed.
If you feel a mistake has been made in applying the rubric on a homework or exam, you may submit a specific, concise, concrete regrade request via Gradescope within one week of receiving the original grade. Consult the official solutions, peers, Zulip, and/or office hours before submitting a regrade request.
