Dijkstra's Algorithm works on the basis that any subpath B -> D of the shortest path A -> Dbetween vertices A and D is also the shortest path between vertices B and D. Djikstra used this property in the opposite direction i.e we overestimate the distance of each vertex from the starting vertex. Then we visit each node … See more We need to maintain the path distance of every vertex. We can store that in an array of size v, where v is the number of vertices. We also want to be able to get the shortest path, not … See more The implementation of Dijkstra's Algorithm in C++ is given below. The complexity of the codecan be improved, but the abstractions are convenient to relate the code with the algorithm. See more Time Complexity: O(E Log V) where, E is the number of edges and V is the number of vertices. Space Complexity: O(V) See more WebDec 1, 2024 · Dijkstra's algorithm is one of many graph algorithms you'll come across.
