<｜begin▁of▁sentence｜>### Instruction:
Given a networkx erdos_renyi_graph with params n=800, p=0.15, can you use NonBackTrackingRandomWalkSampler to sample a subgraph which has 30 nodes and find a dominating set for the graph G ?
### Response:
import networkx as nx
from littleballoffur import NonBackTrackingRandomWalkSampler

G = nx.gnp_random_graph(n=800, p=0.15)

sampler = NonBackTrackingRandomWalkSampler(30)

sampler_G = sampler.sample(G)

result = nx.dominating_set(sampler_G)

print(result)
