Iterative A* search and iterative deepening A* search are related concepts, but they are not exactly the same. Let me explain both concepts and provide you with a simple Python implementation for each. 1. **Iterative A* Search:** Iterative A* search is an improvement over the traditional A* search algorithm. A* (A-star) search is a popular graph traversal and pathfinding algorithm that efficiently finds the shortest path between two points on a graph. Iterative A* search is an enhancement to the A* algorithm where it uses an iterative deepening approach to improve its performance. Here's a simplified Python implementation of Iterative A* Search: ```python def iterative_a_star_search(graph, start, goal): max_depth = 0 while True: result = a_star_search(graph, start, goal, max_depth) if result is not None: return result max_depth += 1 def a_star_search(graph, start, goal, max_depth): # Your A* search implementation goes here # Use max_depth as a limit for the depth of the search # Return the result or None if no path is found within the given depth # Example usage: # result = iterative_a_star_search(graph, start_node, goal_node) ``` 2. **Iterative Deepening A* Search:** Iterative Deepening A* search is a combination of the Iterative Deepening Depth-First Search (IDDFS) and A* search algorithms. It repeatedly performs depth-limited searches, gradually increasing the depth limit until a solution is found. Here's a simplified Python implementation of Iterative Deepening A* Search: ```python def iterative_deepening_a_star_search(graph, start, goal): depth_limit = 0 while True: result = a_star_search(graph, start, goal, depth_limit) if result is not None: return result depth_limit += 1 def a_star_search(graph, start, goal, depth_limit): # Your A* search implementation goes here # Use depth_limit as a limit for the depth of the search # Return the result or None if no path is found within the given depth # Example usage: # result = iterative_deepening_a_star_search(graph, start_node, goal_node)
Best explanation of A* algo! Thanks ma'am!
Love the way you explained ! Simple & easily understandable 💟 Within 10 minutes, I came to know what A* Algo is 💟
Good explanation and good voice!
Thank for sharing 🔥
Thanks for your explanation
thx so much for explaining clearly
i need a video on how heuristic value is calculated
good explanation with cool voice
thank you
very helpful
thank you queen finally I understand
good explanation
Perfect
how do you visit a node like B two
times?
when you website is coming sadiasiddiqui???
excellent video, strange name for a computer science youtube channel
Couldn't come up with a better name 😂
Thank you so much
mam here b is already explored na mam so how can we choose s->a->b mam
make videos on Machine learning MU engineering
can u teach us react full course with advanced concepts
heristic valuse diya rahta hai kya ?
Heuristic value please
When did you cross S ==> A?
she forget to cross the S => A initially , the right time to cross it when you use the S => A and move forward .
❤️❤️❤️
7:09 why didnt we use S->A->D
because it is already reached the goal node and it is not the shortest path
I have been asking you to take a course on alogorithms and database..
How to find heuristic value mam
Heuristic values are given
I have a very urgent doubt please solve it asap
Iterative A* search and iterative deepning A* search has same algorithm
Please solve it 🙏 😔

Iterative A* search is an improvement over the traditional A* search algorithm. A* (A-star) search is a popular graph traversal and pathfinding algorithm that efficiently finds the shortest path between two points on a graph. Iterative A* search is an enhancement to the A* algorithm where it uses an iterative deepening approach to improve its performance.

```python
def iterative_a_star_search(graph, start, goal):
max_depth = 0
while True:
result = a_star_search(graph, start, goal, max_depth)
if result is not None:
return result
max_depth += 1
def a_star_search(graph, start, goal, max_depth):
# Your A* search implementation goes here
# Use max_depth as a limit for the depth of the search
# Return the result or None if no path is found within the given depth
# Example usage:
# result = iterative_a_star_search(graph, start_node, goal_node)
```

result = a_star_search(graph, start, goal, depth_limit)
if result is not None:
return result
depth_limit += 1
def a_star_search(graph, start, goal, depth_limit):
# Your A* search implementation goes here
# Use depth_limit as a limit for the depth of the search
# Return the result or None if no path is found within the given depth
# Example usage:
# result = iterative_deepening_a_star_search(graph, start_node, goal_node)

I need theory part
we need a complete course you teach better
I guess you were in PICT
far better than gate smasher
