So far, there have been many research efforts on the shortest path finding problem. For instance, [A.sup.*] algorithm estimates neighboring nodes using a heuristic function and selects minimum cost node as the closest one to the destination. Pruning method, which is known to outperform the [...
We close this section by showing that Algorithm 1 terminates with a completely pruned graph also in settings different from the one considered here. For general graphs\mathscr {G}^*, an edge\{l_1,l_k\}is redundant if and only if there is a pathP=[l_1 - l_2 - \cdots - l_k]t...

To connect branches that became disconnected due to thresholding, each skeletonized image was turned into a graph using the minimum spanning tree (MST) algorithm (scipy.sparse.csgraph.minimum_spanning_tree (Virtanen et al., 2020)), which connects all points using the shortest path possible, with...
Thus, a completely automatic approach for these hard situations is highly desirable.We have developed an automatic graph algorithm, called the all-path pruning (APP), to trace the 3D structure of a neuron. To avoid potential mis-tracing of some parts of a neuron, an APP first produces an ...
we develop an optimal distributed routing algorithm; we prove that $3Torus(m,n)$ has connectivity 3 and is Hamiltonian; we obtain a precise expression for (an upper bound on) the wide-diameter; and we derive optimal one-to-all broadcast and personalized one-to-all broadcast algorithms und...

Then, in the connecting phase, a tree-based connecting algorithm (TCA) is proposed to build the high-tier network connectivity. TCA first builds a shortest path tree to connect the relays deployed by SPA to the sink, and then, saves the deployed relays by gradually pruning or substituting ...
Search algorithms often suffer from exploring areas which eventually are not part of the shortest path from the start to a goal. Usually it is the purpose of the heuristic function to guide the search algorithm such that it will ignore as much as possible of these areas. We consider other,...
This algorithm reduces the consumption of energy by pruning and establishes the shortest path that leads to efficient network and enables security.doi:10.1007/s11277-016-3249-1Usha, M.Vanitha, C. N.Springer USWireless Personal Communications
