The Edmonds-Karp algorithm is a special way to use the Ford-Fulkerson method. It uses something called breadth-first search (BFS). Here are some reasons why someone might choose Edmonds-Karp instead of Ford-Fulkerson:

1. Faster Calculation Time:

   • Edmonds-Karp has a time complexity of $O(VE^2)$. This means if you have a set number of points (vertices) and connections (edges), you can figure things out faster. This is especially helpful in dense graphs, while Ford-Fulkerson can sometimes take much longer in specific cases.

2. Always Finishes:

   • Sometimes networks can have strange capacities that create endless routes. But with Edmonds-Karp, you can be sure it will eventually finish and give you an answer.

3. Easy to Use:

   • The BFS method in Edmonds-Karp is simple and usually easier to understand and use than the general Ford-Fulkerson method, which can be more complicated.

4. Great for Graphs with Small Capacities:

   • If every connection in the graph has a capacity of one, Edmonds-Karp can quickly find the maximum flow in only $O(E^2)$ time, which is very efficient.

In short, Edmonds-Karp is great when you need something that works quickly, is easy to understand, and always gives you an answer. That's why it can be a better choice in some situations compared to the Ford-Fulkerson method.
