## Challenging aspects
### Challenging aspects in above code
1. **Graph Representation**:
- Understanding how graphs are represented using adjacency lists (`defaultdict(list)`).
- Handling directed vs undirected graphs (in this case it wraps around like a circular linked list).
2. **Floyd-Warshall Algorithm**:
- Properly initializing distance matrices with correct values (0 for self-loops, 1 for direct edges).
- Handling infinite distances (`float('inf')`) appropriately when no direct path exists.
- Implementing nested loops correctly for updating shortest paths.
3. **Edge Cases**:
- Ensuring that self-distances remain zero.
- Correctly updating distances considering all intermediate nodes.
- Handling disconnected graphs where some nodes might remain unreachable.
### Extension
1. **Dynamic Graph Updates**:
- Allow adding/removing edges dynamically and efficiently update shortest paths without recomputing from scratch.
2. **Weighted Graphs**:
- Extend functionality to handle weighted edges rather than assuming all edges have weight `1`.
3. **Path Reconstruction**:
- Implement functionality to reconstruct and return actual shortest paths (not just their lengths).
## Exercise
### Problem Statement
You are tasked with extending the given implementation of the Floyd-Warshall algorithm [SNIPPET] to handle dynamic updates and weighted graphs efficiently.
#### Requirements:
1. **Dynamic Edge Updates**:
- Implement methods `add_edge(u, v, weight)` and `remove_edge(u, v)` that update shortest paths efficiently when an edge is added or removed.
2. **Weighted Graphs**:
- Modify the initial implementation so that edges can have arbitrary weights provided by an additional parameter.
3. **Path Reconstruction**:
- Extend the algorithm so that it can reconstruct and return the actual shortest paths between nodes.
#### Constraints:
- Assume that all weights are non-negative integers.
- You should not recompute shortest paths from scratch after every update.
- The number of nodes ( n ) will be up to (1000).
### Full exercise here
Implement an advanced version of Floyd-Warshall algorithm considering dynamic updates and weighted edges.
python
from collections import defaultdict
import copy
# [SNIPPET]
def create_weighted_graph(num_agents):
"""
Creates a weighted graph with num_agents number of nodes.
Edges are added between nodes that are one step away from each other,
with random weights assigned.
"""
import random
graph = defaultdict(list)
# Connect every node to its two neighbors (1 step away) with random weights
# The graph wraps around so node 0 is connected to node num_agents - 1
def add_edge(graph, u, v, weight):
graph[u].append((v, weight))
graph[v].append((u, weight)) # Assuming undirected graph
weights = [random.randint(1,10) for _ in range(num_agents)]
for i in range(num_agents):
add_edge(graph,i,(i+1)%num_agents ,weights[(i+1)%num_agents])
add_edge(graph,i,(i-1)%num_agents ,weights[(i-1)%num_agents])
return graph
def floyd_warshall_with_path_reconstruction(graph):
"""
Extends Floyd-Warshall algorithm with path reconstruction capability.
Returns:
A tuple containing distance matrix and path reconstruction matrix.
The path matrix can be used to reconstruct actual shortest paths.
Example Usage:
dist_matrix = [[...], [...], ...]
path_matrix = [[...], [...], ...]
path = reconstruct_path(path_matrix, u, v)
where path[u][v] gives list [u,...v]
Note that path[u][u] should be [u]
Input:
graph : adjacency list representation of weighted undirected graph
Output:
distances : dictionary representing shortest distances between all pairs of nodes.
paths : dictionary representing next node on shortest path between any two nodes.
If there is no path between two nodes then distance should be float('inf')
And path should be None
Both distances[u][v] == float('inf') & paths[u][v] == None implies there is no path
Initial setup:
Distance from each node to itself should be set as zero.
Distance between directly connected nodes should be set as their edge weight.
Distance between all other pairs should initially be set as infinity.
Path Reconstruction logic:
If there exists direct connection then next node would be destination itself else next node would be intermediate node
Updating Distances & Paths logic:
For each pair (i,j) try improving distance by trying all possible intermediates k
If new_dist := dist[i][k] + dist[k][j] < dist[i][j]:
Update distance matrix : dist[i][j] := new_dist
Update path matrix :
If there exists direct connection then next node would be destination itself else next node would be intermediate node
i.e., if dist[i][k]+dist[k][j]
