Graph Representation

Learn how to model graphs using adjacency lists, adjacency matrices, and edge lists in Python.

Graph Algorithms Cheat Sheet

Core graph traversal and shortest-path algorithms — BFS, DFS, Dijkstra — with adjacency list representations and complexity comparisons.

Adjacency List vs Adjacency Matrix: When Would You Use Each?

An adjacency list stores, for each vertex, only the list of its actual neighbors, using O(V + E) space that scales with how connected the graph really is, whil…

What Are the Main Graph Representation Techniques?

The two main graph representation techniques are the adjacency list, which stores each vertex with a list of its neighbors and is space-efficient at O(V + E),…
