الملخص
The content delves into the PSRO framework, discussing its historical context, strategy exploration challenges, and applications across various domains. It highlights the synthesis of ideas from different research communities and presents various PSRO variants tailored to different game types. The survey also addresses key issues such as overfitting, diversity measures, joint MSS-RO impact, evaluation methods, training efficiency improvements, and open research questions for future exploration.
الإحصائيات
"In recent decades, the exploration of multiagent systems has been a central focus in Artificial Intelligence (AI) research."
"Understanding their behavior in games is often referred to as game reasoning."
"This survey provides a comprehensive overview of a fast-developing game-reasoning framework for large games, known as Policy Space Response Oracles (PSRO)."
"As an alternative to traditional equilibrium computation methods, to reason about such huge games, a wide range of learning methods have been applied."
"Numerous PSRO variants have been developed, each tailored to leverage the specific characteristics of the underlying games."
"A multiagent system comprises multiple decision-making agents that interact within a shared environment."
"To understand the strategic behavior among these agents – where the optimal behavior of one agent depends on the behavior of others – game theory provides a mathematical framework that defines behavioral stability through solution concepts like the Nash equilibrium (NE)."
"Unlike for general-sum games, for zero-sum games, a sample equilibrium already provides valuable insights into effective strategic play."
اقتباسات
"In PSRO, a key concept is an empirical game model, which acts as an approximation of the underlying full game."
"PSRO alternates between the analysis of the current game model and defining a new learning target."
"Algorithms inspired by PSRO have reached state-of-the-art performance in large-scale games."
