Can you explain what a heuristic is in the context of the A* algorithm?
Sure! A heuristic in the A* algorithm is a function that estimates the cost to reach the goal from a given node.
How does the heuristic affect the performance of the A* algorithm?
The heuristic influences the efficiency of the search. A good heuristic can significantly reduce the number of nodes explored.
Can you give an example of a common heuristic used in A*?
A common heuristic is the Euclidean distance, which calculates the straight-line distance between two points.
What happens if the heuristic is not accurate?
If the heuristic is not accurate, it can lead to longer search times and may even result in suboptimal paths.
