TLDR
It is shown that while the problem of deciding satisfiability of an S5 formula with one agent is NP-complete, the problem for many agents is PSPACE-complete and the problem becomes complete for exponential time once a common knowledge operator is added to the language.

Intelligent Agents: Theory and Practice

TL;DR: Agent theory is concerned with the question of what an agent is, and the use of mathematical formalisms for representing and reasoning about the properties of agents as discussed by the authors ; agent architectures can be thought of as software engineering models of agents; and agent languages are software systems for programming and experimenting with agents.

Introduction to Multiagent Systems

TL;DR: A multi-agent system (MAS) as discussed by the authors is a distributed computing system with autonomous interacting intelligent agents that coordinate their actions so as to achieve its goal(s) jointly or competitively.

Agent theories, architectures, and languages: a survey

TL;DR: A survey of what the authors perceive to be the most important theoretical and practical issues associated with the design and construction of intelligent agents is presented.

Reaching agreements through argumentation: a logical model and implementation

TL;DR: A logical model of the mental states of the agents based on a representation of their beliefs, desires, intentions, and goals is presented and a general Automated Negotiation Agent is implemented, based on the logical model.

Reasoning about knowledge and probability

TL;DR: This work provides a complete axiomatization for reasoning about knowledge and probability, proves a small model property, and obtains decision procedures for adding common knowledge and a probabilistic variant of common knowledge to the language.

The complexity of theorem-proving procedures

TL;DR: It is shown that any recognition problem solved by a polynomial time-bounded nondeterministic Turing machine can be “reduced” to the problem of determining whether a given propositional formula is a tautology.

Some philosophical problems from the standpoint of artificial intelligence

TL;DR: In this paper, the authors consider the problem of reasoning about whether a strategy will achieve a goal in a deterministic world and present a method to construct a sentence of first-order logic which will be true in all models of certain axioms if and only if a certain strategy can achieve a certain goal.

The knowledge complexity of interactive proof systems

TL;DR: A computational complexity theory of the “knowledge” contained in a proof is developed and examples of zero-knowledge proof systems are given for the languages of quadratic residuosity and 'quadratic nonresiduosity.

Is Justified True Belief Knowledge

TL;DR: In this paper, the necessary and sufficient conditions for someone's knowing a given proposition were discussed in a form similar to the following: IFF P is true, IFF S believes that P, and S is justified in believing that P.

Propositional dynamic logic of regular programs

TL;DR: A formal syntax and semantics for the propositional dynamic logic of regular programs is defined and principal conclusions are that deciding satisfiability of length n formulas requires time d n /log n for some d > 1, and that satisfiability can be decided in nondeterministic time cn for some c.
