Category : adjacency-list

I want to make a C++ program on creating a graph using an adjacent list. So I made this: #include<bits/stdc++.h> using namespace std; struct listNode{ int vertexNumber; listNode *next; }; struct graph{ int v; int e; listNode*adj; }; struct graph *adjListofGraph(){ int i,x,y; listNode *temp; graph *g = (graph*)malloc(sizeof(graph)); if(!g){ cout<<"memory error"; return NULL; } ..

I am currently trying to write an algorithm which runs a depth first search by traversing through an adjacency list which holds the vertices and edges of a directed graph. When I print out the adjacency list I know I am storing the information correctly in an array of linked lists, but when I run ..

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 ..

I’m reading the documentation about adjacency_list and the impact choosing the graph type has on memory consumption, big-O runtime, and descriptor stability. Quoting the first link: The following table summarizes which operations cause descriptors and iterators to become invalid. In the table, EL is an abbreviation for OutEdgeList and VL means VertexList. The Adj Iter ..

I’m trying to do some analysis on the time complexity of Kosaraju and Tarjan algorithm to find strongly connected components in a directed graph but the process of making up the graph is taking too much time[ i have to type the "g.add_edge(x,y)" over and over]. I tried using a loop but then how’d i ..
