How to get List of Paths found during DFS

I want to get the list of paths that have been walked during Compute in the following snippet.


var algo = new DepthFirstSearchAlgorithm<FunctionNode, Edge<FunctionNode>>(_graph);

algo.Compute(startNode); //F1

Desired Sample Output: F1->F2->F3; F1->F5

 What is a good way of getting that?

DFS builds a tree rather than a list of path. You can build the list of path from the tree. 

The DepthFirstSearchAlgorithm does not record anything on its own. You need to attach an observer to it. Read the documentation at the bottom of . There is also probably a helper method to extracts path in the AlgorithmExtensions type.

Got it, using TryGetPath, Thanks
