# Why is Dijkstra's Algorithm more popular compared to Grassfire algorithm?

Consider algorithms to find shortest paths in a graph. The grassfire algorithm has a complexity of O(|V|) where V is the number of nodes or vertices. The Dijkstra's algorithm has a complexity of O((|V| + |E|) * log(|V|)) where E is the number of edges. Compared to A star, the Dijkstra's does not rely on properties of any heuristic which makes them popular. But I am trying to understand the advantage of Dijkstra's over Grassfire. Are there practical reasons why this is the case? Or am I simply seeing more cases of Dijkstra's compared to Grassfire due to the application areas such as navigation that I am working on?
