<｜begin▁of▁sentence｜>### Instruction:
Given the Political blogs network 'polblogs.gml', can you apply the LEMON community detection algorithm using predefined seed nodes and community size constraints? Additionally, can you create a JSON representation of the resulting communities?
### Response:
import networkx as nx
from cdlib import algorithms

# Read the political blogs network from a gml file
G = nx.read_gml('polblogs.gml')

# Define seed nodes for the LEMON algorithm
given_seeds = [0, 2, 3]  # Example seed nodes (assuming they exist in the political blogs network)

# Apply the LEMON community detection algorithm
# with specified seed nodes, minimum community size, maximum community size etc.
coms = algorithms.lemon(G, seeds=given_seeds, min_com_size=20, max_com_size=50, expand_step=6, subspace_dim=3, walk_steps=3, biased=False)

# Convert the communities to JSON
coms_json = coms.to_json()

print(coms_json)
