You are a helpful assistant. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer. The reasoning process and answer must be formatted exactly as follows:
<think>
[your reasoning process here]
</think>
<answer>
[your answer here]
</answer>
You can choose to imitate the reasoning process of relevant algorithms or explore an appropriate solution on your own. DO NOT use code, and remember to focus on the logical flow.

Your task is to solve the Maximum Independent Set problem in the given social network. In this network, each node represents a user, and each edge represents a friendship connection. You need to identify the largest subset of users such that no two users in this subset are friends connected by an edge. 

**Problem to Solve**

- Users in the network: Chad Newton, Stephanie Peters, Randy Carter, Sarah Lewis, Mr. Alan Potter MD, Vanessa Price, Luis Nguyen, Robert Brown, Troy Adams, Nicole Johnson, Lisa Guerra, Jonathan Moore, William Shea, Mr. Carl Burton, Wyatt Mckinney, Victor Oliver, Stephen Mejia, Mitchell Webster, Paul Campbell, Andrew Stephens, Anna George, Crystal Willis.
- Fiendship connections: Chad Newton and Paul Campbell, Chad Newton and Anna George, Chad Newton and Crystal Willis, Chad Newton and Mitchell Webster, Chad Newton and Mr. Alan Potter MD, Chad Newton and Robert Brown, Chad Newton and Lisa Guerra, Stephanie Peters and Paul Campbell, Randy Carter and Paul Campbell, Sarah Lewis and Paul Campbell, Mr. Alan Potter MD and Paul Campbell, Vanessa Price and Andrew Stephens, Vanessa Price and Paul Campbell, Luis Nguyen and Paul Campbell, Robert Brown and Paul Campbell, Troy Adams and Paul Campbell, Nicole Johnson and Paul Campbell, Lisa Guerra and Paul Campbell, Jonathan Moore and Paul Campbell, William Shea and Paul Campbell, Mr. Carl Burton and Paul Campbell, Wyatt Mckinney and Paul Campbell, Victor Oliver and Paul Campbell, Stephen Mejia and Andrew Stephens, Stephen Mejia and Paul Campbell, Mitchell Webster and Paul Campbell, Paul Campbell and Andrew Stephens, Paul Campbell and Crystal Willis, Paul Campbell and Anna George, Andrew Stephens and Crystal Willis, Andrew Stephens and Anna George.
