A Fast Implementation of FR-Dijkstra
نویسنده
چکیده
The shortest path problem is the problem of finding the shortest distance from a specified source node to all other nodes in the graph. The best known algorithm for arbitrary graphs with real-valued weights is known as Bellman-Ford, and runs in O(nm) time, where m and n are the number of vertices and nodes in the graph, respectively. For an arbitrary graph with non-negative weights, the best known algorithm is Dijkstra’s algorithm, which runs in O(m+ n log n) time.

Performance of Thorup's Shortest Path Algorithm for Large-Scale Network Simulation
In this paper, we investigate the performance of Thorup’s algorithm by comparing it to Dijkstra’s algorithm for large-scale network simulations. One of the challenges toward the realization of large-scale network simulations is the efficient execution to find shortest paths in a graph with N vertices and M edges. The time complexity for solving a single-source shortest path (SSSP) problem with ...

متن کاملA Fast Algorithm for the Optimal Constrained Path Routing in Wireless Mesh Networks
—Finding a path subject to multiple QoS requirements is regarded as a critical component in wireless mesh networks especially the real-time wireless communication applications become increasingly popular. As far as we know, it is an NPcomplete problem. This paper devises a simple and fast Kapproximation algorithm (KAMCOP) to deal with it from the perspective of approximate. The theoretical val...
متن کاملGraph storage: How good is CSR really?
In the last decade, the data size is growing exponentially and processing those data is becoming a difficult problem. Nowadays researchers and industry have been interested in the analysis of the graph to get deep understanding of social networks. Many of these graphs used in industry have become very large, containing hundreds of millions of nodes and edges. In this paper, I compare Compressed...
متن کاملWE-G-217A-01: Fast Recovery Driven Equilibrium with Automated Switching to Avoid Artifacts.
PURPOSE To reduce image artifacts from the unnecessary use of driven- equilibrium. Driven-equilibrium methods known as fast recovery, RESTORE, or DRIVE enable reduction of repetition time (TR) and hence acquisition time in RARE (FSE or TSE) imaging by applying additional RF pulses following each echotrain to accelerate T1 recovery. Fast recovery (FR) techniques are most useful when TR is less t...
