(Graph Search) Algorithm na Hotuna a ciki Java

Algorithm ɗin Binciken Graph wata muhimmiyar dabara ce a cikin Java shirye-shiryen da ake amfani da ita don nemo madaidaici ko gefuna a cikin jadawali. Jaridu tarin madaidaici ne da aka haɗa ta gefuna. Ana amfani da wannan algorithm sau da yawa akan matsaloli kamar gano hanya mafi guntu, neman haɗin kai tsakanin abubuwa, da nazarin hanyoyin sadarwa.

Yadda Algorithm Binciken Graph ke Aiki

Algorithm ɗin Bincike na Graph yana da hanyoyi daban-daban, kamar Binciken Breadth-First(BFS) da Neman Zurfin Farko(DFS). Duk waɗannan hanyoyin sun haɗa da ƙetarewa da gefuna a cikin jadawali don nemo manufa ko yanayin da ake buƙata.

  • Bincike na Farko-Bredith(BFS) ya fara ratsa tushen tushen bayan haka sannan ya binciko maƙwabcin maƙwabta kafin ya ci gaba zuwa ga nisa.
  • Neman Zurfin Farko(DFS) yana bincika kowane juzu'i kuma yana yin bincike mai zurfi-farko har sai an sami inda ake nufi ko ƙarin bincike ba zai yiwu ba.

Abũbuwan amfãni da rashin amfani Algorithm Search Graph

Amfani:

  • Neman haɗin kai: Wannan algorithm ɗin yana taimakawa gano haɗin kai tsakanin madaidaitan a cikin jadawali, wanda ke da amfani don nemo gajeriyar hanyoyi ko alaƙa tsakanin abubuwa.
  • Ƙarfin bincike mai sauri: Dangane da tsarin jadawali, algorithm na iya bincika manufa da sauri.

Rashin hasara:

  • Mai saurin ɓacewa: A cikin manyan hotuna masu rikitarwa, algorithm na iya zama ɓacewa ko rashin fahimta, wanda zai haifar da bincike mai ɗaukar lokaci.

Misali da Bayani

Yi kwatanta Algorithm ɗin Bincike na Graph ta amfani da Java misalin da ke amfani da hanyar Bincike na Farko(BFS) don nemo mafi guntuwar hanya tsakanin madaidaici a cikin jadawali.

import java.util.*;  
  
public class GraphSearchExample {  
    // Class implementation of the graph and BFS here...  
}  
  
public static void main(String[] args) {  
    Graph g = new Graph(4);  
    g.addEdge(0, 1);  
    g.addEdge(0, 2);  
    g.addEdge(1, 2);  
    g.addEdge(2, 0);  
    g.addEdge(2, 3);  
    g.addEdge(3, 3);  
  
    System.out.println("BFS search from vertex 2:");  
    g.BFS(2);  
}

A cikin wannan misalin, muna ƙirƙira jadawali kuma muna amfani da hanyar Binciken Breadth-First Search(BFS) don nemo haɗe-haɗe daga ɗigon 2. Sakamakon zai zama jerin madaidaitan da aka ratsa ta hanyar nisa-farko daga siti 2. Wannan shine ainihin asali. Hanyar bincike a cikin jadawali ta amfani da Algorithm na Binciken Graph a cikin Java.
