Combinatorics and Optimization

Master two of math’s most powerful techniques.

Hone the skills you need to solve problems in computer science, business, communications, and more.

Combinatorics looks at permutations and combinations. Optimization explores ways to make any operation work more efficiently within given constraints. Together, they provide powerful methods for modelling and solving large management problems, from optimizing flight schedules to making a factory’s layout as efficient as possible.

In Combinatorics and Optimization at Waterloo, you’ll learn concepts such as enumeration, combinatorical designs, graph theory, linear programming, nonlinear optimization, operations research, and combinatorical optimization, and how to use them in real-world applications. Plus, you'll have the opportunity to gain paid work experience through the co-op program.

When you graduate, you can put your skills to work in areas as diverse as cryptography, electronic security, software development, social media, and risk analysis.


Combinatorics and Optimization admission requirements

Apply to Mathematics and choose Combinatorics and Optimization as your major at the end of first year. Once you've applied, you'll need to complete the Admission Information Form as part of the application process.

We strongly encourage you to participate in the Canadian Senior Mathematics Contest and/or the Euclid Mathematics Contest to enhance your admissions status.  

To be considered for entrance scholarships in the Faculty of Mathematics, you must write one or both of the contests. If you complete both contests, we'll use the results of the contest in which you performed best.
