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: Andrea Pagano, Marco Ratto, Zhenzhou Lu, Sergei Kucherenko, Carmen Castillo, Ilya M. Sobol, William Castaings, Enrico Zio, Stefano Tarantola, Emanuele Borgonovo, Sitakanta Mohanty, Jon C. Helton, Luyi Li, Pengfei Wei
- Research collaborations between these authors: Andrea Pagano and Luyi Li, Andrea Pagano and Zhenzhou Lu, Andrea Pagano and Pengfei Wei, Andrea Pagano and Emanuele Borgonovo, Andrea Pagano and Stefano Tarantola, Andrea Pagano and William Castaings, Andrea Pagano and Marco Ratto, Marco Ratto and Luyi Li, Marco Ratto and Zhenzhou Lu, Marco Ratto and Pengfei Wei, Marco Ratto and Emanuele Borgonovo, Marco Ratto and Stefano Tarantola, Marco Ratto and William Castaings, Marco Ratto and Jon C.
