Graph Theory Essentials: Minimum Spanning Trees and Prim's Algorithm

Graphs are the backbone of modern software engineering, powering everything from social networks to GPS routing. Understanding how to find a Minimum Spanning Tree (MST) is a foundational skill for solving complex network design and optimization challenges. This text-based course guides you from absolute graph theory basics to a complete understanding of Prim's algorithm. By reading through clear explanations and structured code walkthroughs, you will gain the confidence to represent graphs and find optimal paths. You will start with core terminology, transition to algorithm logic, and finish with practical, modern implementations. What you'll learn: - Understand fundamental graph concepts, including vertices, weighted edges, and adjacency lists - Define the Minimum Spanning Tree problem and its real-world engineering applications - Trace Prim's algorithm step-by-step using clear, written logical paths - Implement the algorithm in modern Python using type hints and priority queues - Analyze algorithmic complexity to understand how different data structures affect performance - Practice your skills with written exercises and conceptual review questions This course begins with essential definitions of graph properties before introducing the algorithm's core logic. You will then explore step-by-step execution traces and modern, readable code implementations that you can apply directly to your own projects. This course is designed for beginner programmers, computer science students, and self-taught developers who want to master graph algorithms without needing advanced mathematical prerequisites.
