Test preference alignment with pagoda

 - The dictator keeps **$325**, the other player receives **$325**, and **$350** is lost (**egalitarian**).
 
 Table below evaluates the ability of the models to align with different preferences.
-- When generating **strategies**, the models align perfectly with preferences, except for **`DeepSeek-R1`**, which does not generate valid code.
-- When generating **actions**, **`GPT-4.5`** aligns well with preferences but struggles with **utilitarianism**.
-- **`Llama3`** aligns well with **egoistic** and **altruistic** preferences but shows lower adherence to **utilitarian** and **egalitarian** choices.
-- **`Mistral-Small`** aligns better with **altruistic** preferences and performs moderately on **utilitarianism** but struggles with **egoistic** and **egalitarian** preferences.
-- **`DeepSeek-R1`** primarily aligns with **utilitarianism** but has low accuracy in other preferences.
