Dijkstra ’ s shortest paths algorithm Vassos

چکیده
Shown below is pseudocode for Dijkstra’s algorithm. The input is a directed graph G = (V,E) with nonnegative edge weights wt(u, v) for every edge (u, v) ∈ E, and a distinguished node s, called the source (or start) node. The algorithm computes, for each node u ∈ V , the weight of a shortest path from s to u. (It can be easily modified to compute, for each node u, the predecessor of u in a shortest path from s to u, in addition to the weight of such a path.)

k-Link Rectilinear Shortest Paths Among Rectilinear Obstacles in the Plane
We present an algorithm for computing k-link rectilinear shortest paths among rectilinear obstacles in the plane. We extend the “continuous Dijkstra” paradigm to store the link distance information associated with each propagating “wavefront”. Our algorithm runs in time O(kn log n) and space O(kn), where n is the number of vertices of the obstacles. Previous algorithms for the problem had worst...

In order to make the network model was more fitting the actual condition of city traffic, this paper presents a dynamic transportation network model based on the traffic time division, and designs improved Dijkstra algorithm to solve the city traffic paths planning problem. Dijkstra algorithm is a typical singlesource shortest path algorithm is used to calculate a node to all other nodes in the...
متن کاملRecursive Cut and Stitch: Fast All-Pairs Shortest Paths Computation for Subset of Nodes
We present a practical algorithm for computing all pairs shortest paths for subset of nodes on road networks. It provides an important improvement for applications such as traffic analysis, where recomputation of shortest paths is the most expensive step that has to be repeated many times. We propose an algorithm that recursively cuts the graph until pieces are small enough to compute shortest ...

All-Pairs Shortest Paths: Earlier, we saw that Dijkstra’s algorithm and the Bellman-Ford algorithm both solved the problem of computing shortest paths in graphs from a single source vertex. Suppose that we want instead to compute shortest paths between all pairs of vertices. We could do this applying either Dijkstra or Bellman-Ford using every vertex as a source, but today we will consider an a...
متن کاملAn Optimal Algorithm for L1 Shortest Paths Among Obstacles in the Plane (Draft)
We present an optimal Θ(n log n) algorithm for determining shortest paths according to the L1 (L∞) metric in the presence of disjoint polygonal obstacles in the plane. Our algorithm requires only linear O(n) space to build a planar subdivision (a Shortest Path Map) with respect to a fixed source point such that the length of a shortest path from the source to any query point can be reported in ...
