WebMar 4, 2016 · Depth-First Search or DFS; Breadth-First Search or BFS; Uniform Cost Search or UCS; Making graphs. These algorithms can be applied to traverse graphs or trees. To represent such data structures in Python, all we need to use is a dictionary where the vertices (or nodes) will be stored as keys and the adjacent vertices as values. Web10. Wikipedia actually has some pretty good pseudocode for depth-first traversal. These traversal algorithms label all the nodes in the graph with the order they appear in a traversal. You instead want to immediately return the path to the goal when the goal is found. So let's modify the Wikipedia algorithm: dessin des totally spies
