## Why it matters

Modern methods in counting and graph structure; underpins algorithms, network science, CS theory and ML architectures.

## Where it is used

Network analysis, algorithm design, error correction, distributed systems, graph neural networks.

## How you know you have learned it

Solve ≥10 representative problems with ≥80% adjusted accuracy.
