🚨 “Google Maps runs on a 66-year-old algorithm… and it just got dethroned.” When you hit “Directions” in Google Maps, Waze, or Apple Maps, you’re using Dijkstra’s Algorithm, a pathfinding formula from 1959. It’s everywhere: 🌐 The Internet (OSPF routing) ✈️ Airlines & Logistics (shortest-path optimization) 📱 Every GPS app you’ve ever used For 66 years, its runtime of O(m + n log n) was considered the gold standard. Even in 2024, researchers proved it was universally optimal for “sorting-based” approaches… 👉 Until April 2025. What the new team did: 🔹 Dijkstra always processes nodes in strict increasing order of distance. 🔹 This “sorting” step was the bottleneck no one thought could be avoided. 🔹 The new algorithm relaxes this: instead of perfectly sorted order, it groups nodes into carefully chosen “buckets.” 🔹 That clever trick cuts down the sorting overhead and gives a runtime of O(m · log^(2/3) n). 💡 Why this matters: Dijkstra isn’t “wrong”, it’s still in Maps, Waze, and Internet routers. But this shows that even fundamental algorithms can be outpaced. At trillion-edge scale (planetary logistics, AI routing, hyper-optimized networks), this breakthrough is a big deal. If a 66-year-old “untouchable” algorithm can be surpassed… what’s next? [Algorithms ,DataStructure ,ComputerScience ,Engineering ,Dijkstra]
