WebNov 30, 2024 · I am reading the book titled Artificial Intelligence: A Modern Approach by Stuart Russell and Peter Norvig (4th edition) where he explained the difference between a DFS on graph search and on tree search. So the basic difference is that: tree search does not have an explored list to keep track of the visited nodes while graph search does ... WebIn computer science, graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph. Such traversals are classified …

Firstly, we have to understand that the underlying problem (or search space) is almost always represented as a graph (although the underlying graph may not contain cycles, so it may represent a tree). So, the difference is not whether the problem is a tree (a special kind of graph), or a general graph!

To avoid infinite loops, DFS should keep track of the nodes it expanded. That way, it doesn’t explore any node more than once, so it can’t get stuck in a loop. We call that version of DFS a graph-search DFS (GSDFS) since it can handle graphs in general, not just trees. 3. ctf first
