We also discover that the running time of the Generic Dijkstra algorithm in the function of network utilization is not monotonic, as peak running time is at approximately 0.25 network utilization. Additionally, we provide an independent open source implementation of Generic Dijkstra in the Python ...
Dijkstra algorithm. In the last two decade, many variants of A* have been introduced by various researchers to improve the performance of robots working in various environments. Stentz (1995) introduced the first major improvement of A*, focused D* algorithm for real time path replanning...
aDjikstra's algorithm (named after its discover, E.W. Dijkstra) solves the problem of finding the shortest path from a point in a graph (the source) to a destination. It turns out that one can find the shortest paths from a given source to all points in a graph in the same time, ...

The improved Dijkstra algorithm is used for extracting the instantaneous Doppler features of the strongest component in the multi-component echo signal. Then the strongest component is filtered through the time-frequency domain filter. So the instantaneous Doppler ...
Taking the dose as the weights of arcs, the concentrations predicted by CFD are embedded into the modified Dijkstra algorithm to calculate the optimal route with minimal total inhaled dose. The results show that the time before evacuation affects the evacuation route optimization, and the death ...
The lowest risk path is then calculated based on a modified Dijkstra's algorithm. The model is developed and implemented such that it conforms to the Active Dynamic Signage System (ADSS). Herein, a model is designed to monitor the building in real-time and in case of any unexpected event,...

This study proposes a new hybrid time-dependent Dijkstra's and minimum vertex degree algorithm on a spherical bipolar fuzzy weighted graph to find shortest travel time of Hamiltonian cycles on transportation problems. To weight the transportation points in uncertain environment, decision makers can ...
