Adjacency Matrix vs Adjacency List
Developers should learn and use adjacency matrices when working with graph algorithms in applications such as network analysis, social networks, or pathfinding, where quick edge existence queries are needed meets developers should learn and use adjacency lists when working with graph algorithms, such as breadth-first search (bfs), depth-first search (dfs), or dijkstra's algorithm, especially in scenarios like social networks, web page linking, or network routing where graphs are often sparse. Here's our take.
Adjacency Matrix
Developers should learn and use adjacency matrices when working with graph algorithms in applications such as network analysis, social networks, or pathfinding, where quick edge existence queries are needed
Adjacency Matrix
Nice PickDevelopers should learn and use adjacency matrices when working with graph algorithms in applications such as network analysis, social networks, or pathfinding, where quick edge existence queries are needed
Pros
- +They are ideal for dense graphs with many edges relative to vertices, as they provide O(1) time complexity for edge checks, but may be memory-inefficient for sparse graphs
- +Related to: graph-theory, data-structures
Cons
- -Specific tradeoffs depend on your use case
Adjacency List
Developers should learn and use adjacency lists when working with graph algorithms, such as breadth-first search (BFS), depth-first search (DFS), or Dijkstra's algorithm, especially in scenarios like social networks, web page linking, or network routing where graphs are often sparse
Pros
- +It is preferred over adjacency matrices for memory savings and faster neighbor iteration in applications with dynamic edge additions or deletions
- +Related to: graph-theory, data-structures
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Adjacency Matrix if: You want they are ideal for dense graphs with many edges relative to vertices, as they provide o(1) time complexity for edge checks, but may be memory-inefficient for sparse graphs and can live with specific tradeoffs depend on your use case.
Use Adjacency List if: You prioritize it is preferred over adjacency matrices for memory savings and faster neighbor iteration in applications with dynamic edge additions or deletions over what Adjacency Matrix offers.
