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: S. Eswaran, Amir Nahir, David Lin, Sung-Boem Park, Valeria Bertacco
- Research collaborations between these authors: S. Eswaran and David Lin, S. Eswaran and Amir Nahir, S. Eswaran and Sung-Boem Park, S. Eswaran and Valeria Bertacco, Amir Nahir and David Lin, Amir Nahir and Sung-Boem Park, Amir Nahir and Valeria Bertacco, David Lin and Sung-Boem Park, David Lin and Valeria Bertacco, Sung-Boem Park and Valeria Bertacco.
Identify the clique with the maximum number of authors in this network. Present your answer in the following format: [AuthorA, AuthorB, AuthorC, AuthorD, ...].
