Graph theories and algorithms are very helpful for this type of problems. In this paper, we proposed our new SUS_CycleDetection algorithm for detecting cycle in any directed graph, with the help of linked list. This algorithm has the ability to count total number of cycles in the graph ...
Acyclein a sigraphSis said to bepositiveif the product of the signs of its edges is positive or, equivalently, if the number of negative edges in it is even. A cycle which is not positive is said to benegative.A sigraph is said to bebalancedif every cycle in it is positive (Harary...
Prim's algorithm is a method used in computer science to find the minimum spanning tree of a weighted graph. It works by selecting the edge with the smallest weight from the marked vertices in the tree and the adjacent unmarked vertices. ...

The third one is that the model fails to identify direct or indirect risk factors22. Yet, Bayesian networks (BNs), proposed by Pearl Judea, could address the above concerns. BNs constitute a directed acyclic graph (DAG), reflecting potential relationships among influencing factors, and conditional...
Community discovery has emerged during the last decade as one of the most challenging problems in social network analysis. Many algorithms have been propos
We present a simple algorithm that solves Long Directed (s,t)-Path in time O⋆(4.884k). This results also in an improvement upon the previous fastest algorithm for Long Directed Cycle. Introduction Given a digraph (directed graph) G, two vertices s,t∈V(G) and a non-negative integer ...
Graph traversal: DFS How to compute the shortest path between two nodes in an unweighted graph How to detect a cycle in a directed graph How to detect a cycle in an undirected graph How to name a graph with directed edges and without cycle How to name a graph with few edges and with ...
4.3.1 Graph Re-Expression For this example, a design can be automatically generated from the constraints, and each constraint is implemented by a separate phase in a three-phase algorithm: 1. phase1: Map all Node1 elements to Node2 elements. 2. phase2: Map all Edge1 elements to Edge2 ...
For this reason, testing represents an important and valuable phase in the software development life cycle. The main aim of the testing phase is to identify all defects existing in the software under test [1]. However, the defects may come from different sources depending on the application ...
