WebSep 3, 2024 · Introduction. Dijkstra’s algorithm is an algorithm which finds the shortest paths between nodes in a graph. It was designed by a Dutch computer scientist Edsger Wybe Dijkstra in 1956, when he thought about how he might calculate the shortest route from Rotterdam to Groningen. It was published three years later.
