下面是一个使用Python实现LPA算法的简单示例:
```python
import networkx as nx
def lpa(G):
labels = {node: node for node in G.nodes()} # 初始化节点标签
while True:
# 对每个节点进行标签传播
for node in G.nodes():
label_counts = {} # 统计邻居节点的标签数量
# 统计邻居节点的标签数量
for neighbor in G.neighbors(node):
neighbor_label = labels[neighbor]
if neighbor_label in label_counts:
label_counts[neighbor_label] += 1
else:
label_counts[neighbor_label] = 1
# 找到标签数量最多的标签
max_count = max(label_counts.values())
max_labels = [label for label, count in label_counts.items() if count == max_count]
# 随机选择一个最多标签中的标签作为当前节点的新标签
new_label =
