Competing all-pairs shortest paths algorithms for sparse / dense graphs: implementation and comparison

open access: yesСистемный анализ и прикладная информатика
In this paper we consider two families of competing algorithms for finding the shortest paths between all pairs of vertices (APSP) in directed weighted large graphs with different edge densities: Dijkstra and Floyd-Warshall. For comparison, we have taken

Accelerating and analyzing performance of shortest path algorithms on GPU using CUDA platform: Bellman-Ford, Dijkstra, and Floyd-Warshall algorithms

open access: yesНаучно-технический вестник информационных технологий, механики и оптики
The computational demands of the shortest path algorithms on large-scale graphs with millions of vertices and edges pose significant challenges for serial implementations, often requiring hours of execution time even on powerful CPUs.

Fully dynamic all-pairs shortest paths with worst-case update-time revisited

open access: yes, 2016
We revisit the classic problem of dynamically maintaining shortest paths between all pairs of nodes of a directed weighted graph. The allowed updates are insertions and deletions of nodes and their incident edges.

Analysis of optimization waste transportation using saving matrix and floyd warshall methods in Binjai

open access: yesDesimal
Waste is defined as anything that is not utilized or discarded. Waste is not something that happens by itself; instead, it is a product of human activity. Unresolved problems are often caused by waste. Binjai City's waste problem is one example.

Floyd–Warshall Algorithm for Sparse Graphs

open access: yesAlgorithms
The Floyd–Warshall algorithm, which uses a classic dynamic programming approach, provides a solution to the all-pairs shortest paths problem. However, for sparse graphs, iteratively applying Dijkstra’s, or some other similar algorithm from each node ...

Image Redundancy Filtering for Panorama Stitching

open access: yesIEEE Access, 2020
In this paper, we designed a novel framework for massive image panorama stitching, which aims to resolve image redundancy, alignment error accumulation and perspective distortion accumulation of the stitching process.

Extending the Nested Parallel Model to the Nested Dataflow Model with Provably Efficient Schedulers

open access: yes, 2016
The nested parallel (a.k.a. fork-join) model is widely used for writing parallel programs. However, the two composition constructs, i.e. "$\parallel$" (parallel) and "$;$" (serial), are insufficient in expressing "partial dependencies" or "partial ...

Multi-point path planning based on the algorithm of colony-particle swarm optimization

open access: yesTongxin xuebao, 2019
The problem of multi-point path planning is a NP-hard problem,which is equivalent to finding the shortest path of a starting point and some specific node.Aiming at the problem of multi-point path planning,a retrospective ant colony-particle swarm ...
