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: Ryan Jimenez, Kenneth Hodges, Angel Wolfe, Jerome Ferguson, Melissa Hale, Amber Murphy, Scott Webb, David Davenport, Angela West, Travis Baker, Megan Russo, James Edwards, Nicholas Simpson, John White, Maria Howell.
- Fiendship connections: Ryan Jimenez and Melissa Hale, Ryan Jimenez and Nicholas Simpson, Ryan Jimenez and Maria Howell, Kenneth Hodges and Melissa Hale, Kenneth Hodges and Maria Howell, Angel Wolfe and Melissa Hale, Angel Wolfe and James Edwards, Angel Wolfe and Maria Howell, Jerome Ferguson and Melissa Hale, Jerome Ferguson and Nicholas Simpson, Jerome Ferguson and Maria Howell, Jerome Ferguson and Amber Murphy, Melissa Hale and Angela West, Melissa Hale and Amber Murphy, Melissa Hale and Travis Baker, Melissa Hale and Scott Webb, Melissa Hale and James Edwards, Melissa Hale and Nicholas Simpson, Melissa Hale and John White, Melissa Hale and Maria Howell, Amber Murphy and Maria Howell, Scott Webb and Travis Baker, Scott Webb and James Edwards, Scott Webb and John White, Scott Webb and Maria Howell, David Davenport and Maria Howell, Angela West and James Edwards, Angela West and Maria Howell, Travis Baker and James Edwards, Travis Baker and John White, Travis Baker and Maria Howell, Megan Russo and Nicholas Simpson, James Edwards and Maria Howell, John White and Maria Howell.
