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: Gary Levy, Taylor Rogers, Brian Lee, Joyce Griffith, Kurt Davis, Joseph Foster, Christine Gardner, William Robinson, Mary Soto, Joshua Kane, Edwin Henderson, Leah Ruiz, Christine Benson, Valerie Scott, Ruth Mcguire.
- Fiendship connections: Gary Levy and Kurt Davis, Taylor Rogers and Valerie Scott, Brian Lee and Joshua Kane, Brian Lee and Leah Ruiz, Brian Lee and William Robinson, Brian Lee and Kurt Davis, Joyce Griffith and Kurt Davis, Kurt Davis and Edwin Henderson, Kurt Davis and Joseph Foster, Kurt Davis and William Robinson, Kurt Davis and Christine Benson, Kurt Davis and Mary Soto, Kurt Davis and Christine Gardner, Kurt Davis and Valerie Scott, Kurt Davis and Ruth Mcguire, Joseph Foster and Leah Ruiz, Christine Gardner and Leah Ruiz, Mary Soto and Edwin Henderson, Joshua Kane and Edwin Henderson, Leah Ruiz and Christine Benson, Leah Ruiz and Ruth Mcguire.
