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.

You are required to solve the Maximum Clique Problem for an undirected academic network. In this network, nodes represent authors and edges represent research collaborations. Your objective is to find the largest subset of nodes such that every pair of vertices in this subset is connected by an edge.

**Problem to Solve**

- Authors in the network: Takis Sakkalis, Thomas J. Peters, Lars-Erik Andersson, Sunghee Choi, John A. Roulier, Vadim Shapiro, Tamal K. Dey, Neil F. Stewart, Di Jiang, Malika Zidani, Alexander Russell, Nina Amenta, Jian Li, Peter Schröder
- Research collaborations between these authors: Takis Sakkalis and Alexander Russell, Takis Sakkalis and Thomas J. Peters, Takis Sakkalis and Vadim Shapiro, Takis Sakkalis and Nina Amenta, Takis Sakkalis and Sunghee Choi, Takis Sakkalis and Tamal K. Dey, Thomas J. Peters and Jian Li, Thomas J. Peters and Alexander Russell, Thomas J. Peters and Nina Amenta, Thomas J. Peters and Sunghee Choi, Thomas J. Peters and Tamal K. Dey, Thomas J. Peters and John A. Roulier, Thomas J.
