A* Star Algorithm with Python

🌟 This is Part 5 of our Python Graph series. In the last video, we built Dijkstra's Algorithm - the "Accountant" that finds the cheapest path by counting every penny. In this video, we are going to do something even cooler: we will upgrade that exact same code into A-Star. We do not need to rewrite the whole algorithm! We will see how adding just one simple variable - a Heuristic (guess) changes the entire behavior of our search. We will transform our "accountant" into a "smart compass" that knows exactly which direction to go, prioritizing the most promising paths first (f = g + h). 📚 What you will learn: * The difference between Dijkstra (Blind Search) and A* (Heuristic Search) * How to refactor Dijkstra code into A* with minimal changes * Bonus - where to fix the old Dijkstra code from the previous video, as it had some indentation errors. 🧪 Tech stack: * Python 3 * Jupyter 🧮 The set of videos and articles for Graph Theory: ▶️ Graph Theory Set: https://youtu.be/gwUDbV_VGI0 https://youtu.be/tNVU9HSyVxE https://youtu.be/e0RBEHvAI_4 https://youtu.be/VjA_VFO_I6g A* Star Algorithm with Python - This one! https://youtu.be/-rlHYNPQhyQ ▶️ Other (older), related to graph theory: https://youtu.be/DVgqA8-c1oI https://youtu.be/8vnu_5QRC74 https://www.vitoshacademy.com/vba-depth-first-search-algorithm-with-vba https://www.vitoshacademy.com/python-get-the-shortest-path-in-a-weighted-graph-dijkstra/ ▶️ Video with A-Star, just solving it in Excel and listening to music. https://youtu.be/yAx6QGoOdIs 📍 Links 📝 VitoshAcademy blog: https://www.vitoshacademy.com/python-a-star-search-in-graph/ 📝 GitHub code: https://github.com/Vitosh/Python_personal/tree/master/YouTube/048_Python-Graph 👍 Like, 💬 Comment, and 🔔 Subscribe for more real-world programming tutorials. #python #a-star #algorithms #coding #graphtheory
