Hello everyone, a weird issue is occurring with me. I am making a program that will read a file (Vertex file) that has one word per line and will construct an adjacency matrix representation of a graph. there are 5757 words in the file. Then in another file (Edge File) has the edges between the ..

I have an adjacency matrix for a graph. And I need to output all the cycles in this graph. How can I do this using dfs? void al_dfs(int tmp_vertex,int** Graph,vector<int>& color,int number,vector<int>& result){ color[tmp_vertex] = 1; for(int i = 0;i<number;i++){ if((color[i] == 0)){ al_dfs(i,Graph,color,number,result); result.push_back(i); }; if((color[i] == 1)){ for(int i = 0;i< result.size();i++) cout ..
I am new to C++ programming and have an assignment where a file with a set of values is taken in and used to create an adjacency graph. The .txt file is like so 1 3 22.5 3 1 22.5 8 5 14.2 3 5 2.5 The instructor is asking us to use an Unordered ..
In the boost graph library, there are two popular functions to read in graphs from a file: boost::read_graphviz(), and boost::read_graphml(), for the GraphViz and the GraphML format, respectively. Now both read generically to any type of boost::adjacency_list<…>, as they are derived from the Mutable Graph concept: #include <string> #include <fstream> #include <boost/graph/adjacency_list.hpp> #include <boost/graph/adjacency_matrix.hpp> #include ..
Here is my Graph class which contains adjacency list: typedef std::vector<std::list<unsigned int>> AdjacencyList; class Graph { public: Graph(size_t vertices); // to test // Constructs a ‘Graph’ object, // expecting a pointer to the ‘AdjacencyList’ // and the number of vertices Graph(std::shared_ptr<AdjacencyList> adjListPtr, int vertices); // to test // Constructs a ‘Graph’ object from ‘AdjacencyMatrix’ object ..
I need to find the best sorted array, given an array of consecutive integers that start from 0 and a symmetric matrix describing at every position the array items scores. matrix[row][col] is the score of items row and col in the given array. the matrix is like an adjacency matrix but with similarity scores. for ..
Suppose in a social media network: N is friends with K, P, U, X X is friends with N, A, B and C U is friends with A, B and N A is friends with P, U and X B is friends with X and U P is friends with K, N and A K ..
I’m trying to write a simple program to calculate betweenness centrality . I got stuck at getting an output . I read an article to do this but I couldn’t set up its algorithm. adjacency matrix code I created Screen output should look like this(sample is not real values) | Nodes | betweenness centrality | ..
Need to transform given adjacency matrix to incidence , have func to make adj matrix , but don’t know how to transform it . Trying to transform it to incidence by this func , but nothing work : class Graph { public: int verticles; int edges; int** adjMatrix; void IncMatrix(int verticles,Graph graph) { int** matrix ..
Trying to take an adjacency relation with this input format {(1,2),(1,5),(2,1),(2,3),(3,2),(3,4),(4,3),(4,5),(5,1),(5,4)} and print a adjacency matrix. My goal was to check for digits using isdigit() and then take the 2 numbers and update my matrix in those indexes. My matrix still results with all 0’s. To test input. 6 as nodes and enter the above ..
