Graph Representations and Traversal
A graph G = (V,E), where V is the set of vertices, and E is the set of edges. An edge e ∈ E is an unordered pair (u,v) in undirected graphs, where u,v∈V . In directed graphs, an edge e is an ordered pair. A path from a vertex u to a vertex v is a sequence of vertices (w0,w1, ...wk), where u = w0, v = wk and (wi−1,wi) ∈ E for all 1 ≤ i ≤ k. The path is a cycle if u = v. The length of a path in a...
متن کاملThe Graph Traversal Pattern
A graph is a structure composed of a set of vertices (i.e. nodes, dots) connected to one another by a set of edges (i.e. links, lines). The concept of a graph has been around since the late 19th century, however, only in recent decades has there been a strong resurgence in both theoretical and applied graph research in mathematics, physics, and computer science. In applied computing, since the ...
متن کاملGraph Traversal and Linear Programs
Besides breadth first search, which we saw in class in relation to Dijkstra’s algorithm, there is one other fundamental algorithm for searching a graph: depth first search. To better understand the need for these procedures, let us imagine the computer’s view of a graph that has been input into it, in the adjacency list representation. The computer’s view is fundamentally local to a specific ve...

متن کاملGraph Passing in Graph Transformation
Graph transformation works under the whole world assumption. Therefore, in realistic systems, both the individual graphs and the set of all such graphs can grow very large. In reactive formalisms such as process algebra, on the other hand, each system is split into smaller components which continually interact; the interactions pass information such as names or locations between components. The...
