A 41-year-old computer science barrier just broke. For decades, shortest-path algorithms lived under the shadow of Dijkstra’s “sorting barrier.” It was considered a hard limit — something you optimize around, not break. Now, a research team from Tsinghua University has shown that this limit was never fundamental. No flashy name yet. No hype cycle. Just a quiet algorithmic breakthrough that could reshape how paths are computed in maps, networks, and large-scale systems. Most people will scroll pa

Luminica | AI & Tech Demos on Instagram: "👀 Every computer science graduate learned Dijkstra’s algorithm. Tsinghua just proved the textbooks incomplete. For 40 years, researchers believed they hit a fundamental limit called the „sorting barrier.“ To find the shortest path, you had to sort. No way around it. Robert Tarjan, a Turing Award winner, optimized it in 1984. That was the ceiling. Everyone accepted it. Until a Tsinghua team tried something „stupid“ - using the slower Bellman-Ford algorit
