add (multigraph)

Enter title

Enter text for each vertex in separate line

Setup adjacency matrix. Use comma "," as separator

Multigraph matrix contains weight of minimum edges between vertices.

Matrix is incorrect. Use comma "," as separator. Matrix should be square

Set up incidence matrix. Use comma "," as separator.

Matrix is incorrect. Use comma "," as separator.

What functions should we add firstly?

Please, write what kind of algorithm would you like to see on this website?

Our service already supports these features: Find the shortest path using Dijkstra's algorithm, Adjacency matrix, Incidence Matrix.
