Question
Python code for the following problem.
The format needs to be the same as the instructions. eg:
def approximation(g):
n = g.number_of_nodes()
Need to use function "nx.minimum_spanning_tree(g)" and command "list(nx.dfs_preorder_nodes(graph, 0))".
Thank you.
Transcribed Image Text:Implement an approximation algorithm for the Traveling Salesman problem, which outputs a solution which is a 2-approximation of the optimal weight.

import networkx as nx

# This function takes as input a graph g.
# The graph is complete (i.e., each pair of distinct vertices is connected by an edge),
# undirected (i.e., the edge from u to v has the same weight as the edge from v to u),
# and has no self-loops (i.e., there are no edges from i to i).

# The function should return a 2-approximation of an optimal Hamiltonian cycle.

def approximation(g):

# n is the number of vertices.
12
n = g.number_of_nodes()

# You might want to use the function "nx.minimum_spanning_tree(g)"
15
# which returns a Minimum Spanning Tree of the graph g
16
17
# You also might want to use the command "list(nx.dfs_preorder_nodes(graph, 0) )"
18
# which gives a list of vertices of the given graph in depth-first preorder.
