Graphynx Lite

Graphs and algorithms

Create graphs (simple, weighted, directed and/or multigraphs) and run algorithms step by step. Learn graph theory interactively... much better than a book!

27 algorithms to choose from (some of them are only available in the full version):

- Depth-first search (DFS)

- Breadth-first search (BFS)

- Count connected components (using BFS)

- Greedy coloring

- BFS coloring

- Dijkstra's algorithm (shortest path)

- A*/A-star (shortest path, Euclidean distance)

- DFS spanning tree

- BFS spanning tree

- Prim's algorithm (minimum spanning tree)

- Kruskal's algorithm (minimum spanning tree/forest)

- Bridge edges finding

- Articulation points/cut vertices finding

- Eulerian graph detection

- Semi-Eulerian graph detection

- Tarjan's algorithm for strongly connected components in directed graphs

- Tree detection

- Bipartite graph detection

- Complete graph detection

- Tree center (unweighted graph)

- Tree center (weighted graph)

- Tree radius

- Tree diameter

- Tree node eccentricity

- Tree centroid

- Complement (inverse) graph

- Fleury's algorithm (Eulerian cycles/paths in Eulerian and semi-Eulerian graphs)

...and more to come!
