<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(0, 1), (1, 2), (2, 3), (3, 0)], can you use the vertex cover function in igraph to get a summary of the vertex cover?
### Response:
import igraph as ig

# Create a graph
g = ig.Graph(edges=[(0, 1), (1, 2), (2, 3), (3, 0)])

# Compute the minimum vertex cover using an approximation algorithm
vertex_cover = g.mincut().add_partition(0).partition
print(vertex_cover)

# Get a summary of the vertex cover
summary = vertex_cover.summary()
print(summary)
