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)
Good explanation and good voice!
Love the way you explained ! Simple & easily understandable 💟 Within 10 minutes, I came to know what A* Algo is 💟
Best explanation of A* algo! Thanks ma'am!
fabulous explanation , quick revision for Gate DA aspirants !
life saver i watched like 4 videos and none of them made sense came across yours and was saved thank you smmmmm
Easily understood. Thank you, ma'am :)
i need a video on how heuristic value is calculated
7:09 why didnt we use S->A->D
because it is already reached the goal node and it is not the shortest path
Your voice is mindblowing❤
not only voice bro..
thank you queen finally I understand
can u teach us react full course with advanced concepts
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 .
excellent video, strange name for a computer science youtube channel
Couldn't come up with a better name 😂
Heuristic value please
Thanks for your explanation
Thank for sharing 🔥
good explanation with cool voice
thx so much for explaining clearly
far better than gate smasher
make videos on Machine learning MU engineering
heuristic value video
when you website is coming sadiasiddiqui???
how do you visit a node like B two
times?
mam here b is already explored na mam so how can we choose s->a->b mam
Thank you so much
How to find heuristic value mam
Heuristic values are given
thank you
very helpful
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 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.

```python

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)
How the heuristic values calculated
Given
heristic valuse diya rahta hai kya ?
What to do if heuristic value is not provided?
Make up your own heuristic values.
Perfect
good explanation
How to taake heuristic values
That's the part of the question itself ..you don't need that to calculate on yourself
I have been asking you to take a course on alogorithms and database..
Heuristic values meru ela thisukunaru
Did you get the answer
What's Madam ela ala
I guess you were in PICT
I need theory part
we need a complete course you teach better
samaj agya
❤️❤️❤️
