How to deal with Residual Graphs in SageMath for Edmond-Karp algorithm
I am working with Sagemath and Python to model oriented and non-oriented graphs in Graph Theory. The professor has asked us to write the Edmond-Karp algorithm in Python so as to work out the maximum flow from source to sink in a directed graph. He hinted to use labels in Sagemath to work with residual graphs. I learned about labels and am able to use them but I am no closer to making a residual graph. I'd like to know how I can model a residual graph in Sagemath.
The following is how I am making a graph with labels:
edge_list = [(0, 1, 5), (0, 2, 7), 1(1, 2, 13)];
g1 = DiGraph(edge_list, weighted=True);
g1.show(edge_labels=True);
This shows me an oriented graph with the edges.
Lastly, this may be another question but I'd like to also know if finding the shortest path in Edmond-Karp algorithm, should I consider using Dijikstra?
Thank you :)
