WebMar 1, 2024 · Step by Step Example. Dijkstra’s Algorithm works on weighted, acyclic graphs. Acyclic means that there is no path from a given vertex back to itself, this means that for Dijkstra’s algorithm to work the graph must be directed. Weighted means that there is a value associated with each edge. These weights must be non-negative. orange eshop mdWebMay 26, 2014 · A graph is a set of locations (“nodes”) and the connections (“edges”) between them.
