Dijkstra's Algorithm: Graph Shortest Path step-by-step

Finding the most efficient route is a fundamental challenge in computer science, powering everything from GPS navigation to network routing. This text-based course guides you through the core concepts of graph theory and Dijkstra's algorithm, taking you from basic definitions to writing your own efficient pathfinding code. What you'll learn: - Understand the fundamentals of graphs, vertices, and weighted edges - Grasp the greedy search principle that powers Dijkstra's algorithm - Trace pathfinding execution step-by-step using manual walkthroughs - Implement the algorithm in Python using modern type hints and clean code structures - Optimize performance using priority queues and heap data structures - Analyze time and space complexity to write production-ready code You will start with foundational graph terminology and definitions before moving to manual execution examples, and finally, writing and refining your own clean Python code. This course is designed for beginner programmers and computer science students looking to master core algorithms, with no advanced prerequisites required. Start reading to master one of the most famous algorithms in computer science.
