About CMIMC

What Is the Carnegie Mellon Informatics and Mathematics Competition?

The Carnegie Mellon Informatics and Mathematics Competition (CMIMC) is a challenging mathematics and computer science competition designed for high school students interested in advanced problem solving. Hosted by students at Carnegie Mellon University, CMIMC brings together students to compete in mathematics, computer science, and team-based problem-solving events.

A Competition Combining Mathematics and Informatics

CMIMC stands out by bringing together mathematical reasoning and computer science problem solving. Students are challenged with problems that require logical thinking, creativity, algorithmic reasoning, and the ability to develop efficient solutions.

The competition is particularly appealing to students who enjoy mathematics, programming, algorithms, and computational thinking. Depending on the event, participants may need to apply concepts from areas such as algebra, combinatorics, number theory, geometry, algorithms, and data structures.

Team Problem Solving Students can work collaboratively to analyze difficult problems, develop strategies, and solve challenges under competition conditions.

Why Students Participate in CMIMC

CMIMC gives mathematically and computationally motivated high school students an opportunity to challenge themselves beyond standard classroom coursework and experience a higher level of mathematical and algorithmic problem solving.

Preparing for CMIMC can help students strengthen skills that are valuable across many mathematics and computer science competitions, including AMC, AIME, PUMaC, HMMT, ARML, USAMTS, USACO, and other advanced STEM competitions.

Think Mathematically. Solve Computationally.

CMIMC encourages students to combine mathematical insight with logical and computational thinking. Working through challenging problems can strengthen pattern recognition, algorithmic reasoning, persistence, and the ability to develop solutions to unfamiliar problems. These skills can provide a strong foundation for advanced mathematics, computer science, and future STEM studies.

CMIMC Topics

Topics Covered in the CMIMC Competition

CMIMC combines advanced mathematical problem solving with theoretical computer science. Students are challenged across several core areas, with an emphasis on logical reasoning, creativity, problem solving, and applying mathematical or computational ideas in unfamiliar situations.

x

Algebra

Students may encounter equations, inequalities, polynomials, sequences, functions, algebraic identities, and other problems requiring creative algebraic manipulation and logical reasoning.

#

Number Theory

Problems can involve integers, divisibility, prime numbers, modular arithmetic, Diophantine equations, and patterns or properties of numbers.

C

Combinatorics

Counting, arrangements, selections, recursion, invariants, casework, and discrete structures challenge students to find systematic and efficient solutions.

Geometry

Students work with geometric configurations involving angles, triangles, circles, lengths, areas, ratios, and other relationships that require visual and deductive reasoning.

</>

Computer Science

The computer science component emphasizes algorithmic thinking, data structures, graph theory, Boolean logic, pseudocode, and computational problem solving.

Theoretical Computer Science

Advanced problems can explore theoretical computer science, algorithmic reasoning, computational bounds, proofs, and concepts that connect mathematics with computer science.

!

Mathematics Meets Computer Science

CMIMC is distinctive because it combines traditional mathematical competition topics with computer science and theoretical computer science. Students should be prepared to reason through unfamiliar problems, recognize patterns, develop efficient approaches, and communicate mathematical or computational ideas clearly.
