What are some effective techniques for optimizing depth-first search algorithms?
Some effective techniques include pruning, iterative deepening, and using heuristics to guide the search.
Can you explain how pruning works in DFS?
Pruning involves eliminating branches in the search tree that won't lead to a solution, reducing unnecessary exploration.
What is iterative deepening and how does it help?
Iterative deepening combines depth-first search's space efficiency with breadth-first search's completeness by gradually increasing the depth limit.
Are there any specific heuristics that work well with DFS?
Yes, heuristics like the A* algorithm can be adapted to guide DFS by estimating the cost to reach the goal.
