Question: What is the main difference between Dijkstra\'s algorithm and A* search algorithm?

Options:

Correct Answer: A* uses heuristics to improve efficiency

Solution:

The main difference is that A* uses heuristics to guide its search, making it more efficient in many cases compared to Dijkstra\'s algorithm.

What is the main difference between Dijkstra's algorithm and A* search algorithm?

Step 1: Understand that both Dijkstra's algorithm and A* search algorithm are used to find the shortest path in a graph.
Step 2: Learn that Dijkstra's algorithm explores all possible paths from the starting point to find the shortest one without any guesswork.
Step 3: Recognize that A* search algorithm also finds the shortest path but uses a heuristic, which is a smart guess about how close a path is to the goal.
Step 4: Realize that the heuristic in A* helps it to focus on the most promising paths, making it faster and more efficient in many cases compared to Dijkstra's algorithm.
