First Dijkstra's algorithm and then two new modified merge algorithms are derived and presented in detail. The merge algorithms take advantage of natural runs in the input sequence and have a worst case O(n log n ) time complexity when appropriate merging techniques are used, but can be ...
Running Dijkstra’s algorithm with different priority queues does not always find all the same shortest paths. See A note on “consistency” below.The supported priority queues, and their (amortized) asymptotic worst-case running times for the most relevant operations, are:...
The bottleneck of Dijkstra's algorithm is finding the next closest, unvisited node/vertex. UsingLinkedListthis has a complexity ofO(numberOfEdges), since in the worst case scenario we need to go through all the edges of the node to find the one with the smallest weight. To make this bette...
Finding a path (in black) from the top-left node to the bottom-right node of a 50 × 50 grid using influence-aware algorithm (T): (a) without attractors and repulsors, the search space only covers neutral nodes (in cyan) along or close to the path (in black); (b) with 2 attract...
MPMP achieves low EDR and polynomial worst-case time complexity using a modified Dijkstra's algorithm with a metric, called the minimum normalized margin. We show by simulation that MPMP has better performance than two competing schemes from the literature, TAMCRA and H_MCOP....

The third algorithm is the most interesting of these three, but is rather non intuitive. In [8] a proof of its correctness was presented, but the question of determining its worst case complexity – that is, providing an upper bound on the number of moves of this algorithm until it ...

The key findings suggest that while both algorithms can effectively find the shortest path, the Bellman–Ford algorithm is more versatile as it can handle negative weights and visit a vertex more than once, thus providing an optimal path. However, the time complexity of Bellman–Ford was not ...
4.2.2. Maze Complexity Searching in an obstacle course such as a maze with a heuristic technique such as an Ant Algorithm is a process “rich in randomness”, leading to excessively random search statistics (in terms of run time, number of steps, etc.). Therefore, in order to properly as...
