Graphs are crucial mathematical structures for modeling problems, requiring efficient representation for algorithmic solutions. Various methods exist for representing graphs, including adjacency matrices and adjacency lists, each with distinct advantages and disadvantages regarding space and operational efficiency. Understanding these graph representations and their applications forms the foundation for algorithmic problem-solving in computer science.
Graphs consist of vertices connected by edges, which can be directed or undirected.
Adjacency matrices offer a straightforward representation but can be space-inefficient in sparse graphs.
Adjacency lists provide a more compact representation but may require scanning through neighbors to determine connectivity.
A collection of vertices connected by edges.
A graph where edges have a direction, represented as ordered pairs.
A graph where edges do not have direction, represented as unordered pairs.
A square matrix used to represent a graph, where the entry at row i and column j indicates the presence of an edge between vertices i and j.
A representation of a graph where each vertex has a list of its neighbors.
An algorithm for traversing graphs where all neighbors at the current depth are explored before moving on to nodes at the next depth level.
