Dijkstra algorithm is not improved in terms of space and time-complexity, the algorithm is muddled to apply in network analysis for enormous test cases. To handle this huge time complexity, advanced structures are applied to enhance Dijkstra algorithm. The use of a keen and numerical procedure ...

(2018) introduced Dijkstra's algorithm in the field of path planning for driverless cars. The second one is to analyze and improve the time complexity of the algorithm. The traditional Dijkstra's algorithm is inefficient with a long running time, in order to improve the operational efficiency ...
[9] Aaron Hsu has made heavy use of APL in studying parallel algorithms in Co-dfns, and emphasizes its transparent performance characteristics: time and space complexity can usually be obtained directly from an APL expression with little effort. Dijkstra claims that APL is a "bag of tricks"...

If a Fibonacci heap is used, the time complexity can be further improved to O(E + V log V).The space complexity of Dijkstra's algorithm is O(V) since we need to store the distances for all vertices and the priority queue (or equivalent structure).Applications of Dijkstra's AlgorithmDijk...
When is Dijkstra algorithm used? Dijkstra's algorithm is often used to calculate the shortest route between two points on a map, in cases like GPS navigation and traffic routing, computer network routing or AI pathfinding in video games.

Empirical findings reveal that the time complexity of Dijkstra's algorithm is O(V), completing in 0.22s, whereas A-Star achieves a faster execution time of 0.07s with a time complexity of O(E). Regarding space complexity, Dijkstra consumes O(V+E) memory, using 179,241 to 190,961 bytes...
