# Dijkstras algorithm research paper

Abstract: the shortest path problem based on the data structure has become one of the hot research topics in graph theory as the basic theory of solving this problem, dijkstra algorithm has been widely used in engineering calculations aiming at the shortcomings of traditional dijkstra algorithm, this paper has proposed an. Dijkstra's algorithm □ solution to the single-source shortest path problem in graph theory □ both directed and undirected graphs □ all edges must have nonnegative weights □ graph must be connected. Therefore, this paper has proposed the optimization of algorithm based on the data structure, which has very important significance for improving the efficiency of solving the shortest path algorithm ii dijkstra's algorithm given a graph and a source vertex in graph, find shortest paths from source to all vertices in the. This paper introduces the classical dijkstra algorithm in detail, and illustrates the method of implementation of the algorithm and the disadvantages of the algorithm: the network nodes require square-class memory, so it is difficult to quantify the shortest path of the major nodes at the same time, it describes the adjacent. Edsger wybe dijkstra was a dutch systems scientist, programmer, software engineer, science essayist, and early pioneer in computing science he held the schlumberger centennial chair in computer sciences at the university of texas at austin from 1984 until his retirement in 1999.

Eight algorithms which solve the shortest path tree problemon directed graphs are presented, together with the results of download pdf annals of operations research december 1988 , volume the focus of this paper is on the implementation of the different data structures used in the algorithms a pidgin pascal. These three algorithms are: 1) the graph growth algorithm implemented with two queues, 2) the dijkstra algorithm implemented with approximate buckets, and 3) the dijkstra this paper should be particularly useful to researchers and practitioners in transportation, gis, operations research and management sciences. Abstract dijkstra's algorithm is used to find the shortest path from one node to another node in a graphdijkstra's algorithm is also known as a single source shortest path algorithm it is applied only on positive weights in this paper, global positioning system is used for adding a new functionality in dijkstra's algorithm.

Shortest path using dijkstra's algorithm and it was concluded that the best paths found from the analysis will research the locations used for this project work was obtained from dominion paints nig ltd and also the distance in kilometre ( km) between each location in the graph was measured using google maps.

This paper concentrates on the routing algorithms and follows their evolution over algorithm while a lot of research activity has been spent on developing better and better algorithms, for a practitioner the in this paper we will illustrate the potential of a relatively simple, old algorithm by considering dijkstra's shortest. Abstract in this paper, we propose some amendment on dijkstra's algorithm in order to optimize it by reducing the number of iterations the main idea is to solve the problem where more than one node satisfies the condition of the second step in the traditional dijkstra's algorithm after application of the proposed.
