Important graph algorithms : DFS. Graph Theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. The problems considered will be typically motivated by algorithmic/computer science/IT applications. A matching problem arises when a set of edges must be drawn that do not share any vertices. Network science is an academic field strongly rooted in graph theory that is concerned with mathematical models of the relationships between objects. Start the algorithm on any node s, mark s as visited, and iterate over all edges of s , adding them to the (pq) . eCollection 2017. Graph theory algorithms can be traced back over one hundred years to when Fleury gave a systematic method for tracing an Eulerian graph and G. Tarry [1895] showed how to escape from a maze. Algorithm: Store the graph in an Adjacency List of Pairs. The graph theory algorithm is first introduced to solve the WNP problems by Tzatchkov et al.
