This document, "Multiagent Systems Algorithmic, Game-Theoretic, and Logical Foundations," is a comprehensive academic text exploring the foundational principles of multiagent systems. It covers a wide array of topics, beginning with distributed problem solving and progressing into noncooperative game theory, including Nash equilibria and various solution concepts. The book also addresses multiagent learning, different forms of communication between agents, and protocols for groups like social choice theory and mechanism design, particularly auctions. Finally, it introduces coalitional game theory and logical theories for reasoning about knowledge, belief, and intention in multiagent contexts.
