<｜begin▁of▁sentence｜>### Instruction:
Given the Les Miserables co-occurrence network which you can read from a GML file named lesmis.gml, can you use the Genetic Algorithm community detection method in cdlib to perform community detection? And can you output a JSON representation of the resulting community structure?
### Response:
import networkx as nx
from cdlib import algorithms

# Create a graph
G = nx.read_gml('lesmis.gml')

# Apply the Genetic Algorithm for community detection
communities = algorithms.ga(G, population=100, generation=10, r=0.1)

# Generate a JSON representation of the community structure
communities_json = communities.to_json()

print(communities_json)
