  Wendelin Reich: Reasoning About Other Agents
Both agents carry out social meta-reasoning in response to observable behavior and both agents assume that the respective other carries it out (e.g., agent 1 when she interprets agent 2's small adjustment as "goodwill"; agent 2 when he reconstructs agent 1's reconstruction of his own subjective valuation of the good).
Likewise, reasoning such as, "A drastically adjusted price reveals that the agents believes her good is worth little" cannot be represented in classical game theory because it involves incomplete information, and it cannot be represented as a game of incomplete information (e.g., a signaling game, Owen 1995: p.
Thus, agents can be characterized as processes that apply rules to their own properties according to the laws of a specific logical calculus, thereby transforming a set of initial states (e.g., perceptions) into a set of final states (e.g., actions).

  Autonomous learning and reasoning agent
In a preferred embodiment, the autonomous agent may be implemented in a case-based reasoning system, which may be coupled to a sensor for gathering information from, and to an effector for manipulating, its environment (which may comprise a software environment, a physical environment, or some combination thereof).
A software agent 101 may be embedded in an environment 102 so that the agent 101 may receive a stimulus 103 from the environment 102 by receiving a stimulus message 104, and may perform an action 105 which affects the environment 102 by sending an action message 106.
In a preferred embodiment, the software agent 101 may be implemented with an automated processor 124, which may execute a software inference engine 125 for reasoning using a set of cases 126 in a case base 127 and a set of rules 128 in a rule base 129.

 Moral Reasoning (Stanford Encyclopedia of Philosophy)
This article takes up moral reasoning as a species of practical reasoning — that is, as a type of reasoning directed towards deciding what to do and, when successful, issuing in an intention (see entry on practical reason).
When this reasoning by analogy starts to become systematic — a social achievement that requires some historical stability and reflectiveness about what are taken to be moral norms — it begins to exploit comparison to cases that are “paradigmatic,” in the sense of being taken as settled.
From the epistemically limited standpoint of moral reasoning, however, the interesting question, from the point of view of the theory of moral reasoning, is whether agents are authorized by their roles to give special prominence to certain considerations in their moral deliberation and to ignore others.

 Agent or Program   (Site not responding. Last check: 2007-10-29)
A spell checker adjunct to a wordprocessor is typically not an agent for the reasons given in the preceding paragraph.
Agents may also be classified by the range and sensitivity of their senses, or by the range and effectiveness of their actions, or by how much internal state they possess.
For example, when a collection of scheduling agents gather to schedule a meeting between their users, they pursue a common goal and intelligent group behavior emerges (see Kautz, Selman, and Coen 1994 for a similar situation.) Yet, as a group, our definition of agent is not met in that persistence is missing.

 Experiments with an Agent-oriented Reasoning System
Whereas many hard-wired integrations of reasoning systems have been shown to be fruitful, rather few architectures have been discussed so far that try to extend the application range of reasoning systems by a flexible integration of a variety of specialist systems.
The former is achieved by providing a declarative agent specification language and mechanisms supporting the definition, addition, or deletion of reasoning agents (as well as some other proof search critical components and heuristics) even at run-time.
The agent paradigm was chosen to enable a more flexible integration approach, and to overcome some of the limitations of hardwired integrations (for instance, the brittleness of traditional proof planning where external systems are typically called within the body of proof methods and typically do not cooperate very flexibly).

 O-ANTS -- An Agent Based Approach to Reasoning   (Site not responding. Last check: 2007-10-29)
Resource management is employed to distribute available resources amongst the available reasoning agents in order to determine their maximum reasoning time and to prevent them from a quick consumption of all available resources.
Generally our approach supports parallelization of reasoning tasks on term level, inference level, and proof search level and external systems can not only be employed to support object level proof search but also to support meta-level reasoning, for instance, by checking complicate application conditions of inference rules.
The task of the O-ANTS agents (the knowledge sources of the flboards) is to test the applicability of rules, tactics, methods, and external reasoners in a given proof state and to suggest appropriate parameter instantiations for them.

 Intelligent Software Agent Bibliography - Steve Gant   (Site not responding. Last check: 2007-10-29)
Reasoning about intentions is an important area of research for the design of resource bounded rational agents who need to coordinate their actions with the actions of other agents in a multi-agent system.
Commitments ensure that agents reason to achieve their intentions, however a commitment can also be dropped if it is considered irrational by the agent to continue acting for its associated intention.
Guides are a simple form of agents who assume the roles of storytellers, and their success is to be measured not by the stringent requirements of full-blown intelligent agents, but against the softer criteria of plausibility and suspension of disbelief.

 Why explicit knowledge is not enough
Reliability implies that the agent is able to select deterministically a suitable procedure for the input and compute the answer within finite time.
The first question is answered by specifying the logic used by agents in their reasoning, and the second one by a complexity analysis.
What an agent knows or can derive from his knowledge is determined by the logic he uses in his reasoning.

 Invited Lecture, Oct. 2000, Ushuaia, Argentine
Although there have been developed in the last years a huge variety of techniques and methods related to agents, a well-defined theoretical foundation unifying the different facets under one umbrella is still missing.
Agents must be able to reason with beliefs, time, uncertainty and security.
We extend agent programs by beliefs: agents are allowed to have beliefs about others and to use them in their programs: meta agent programs.

 Jaime Simão Sichman: DEPINT: Dependence-Based Coalition Formation in an Open Multi-Agent Scenario
This way, an agent may dynamically choose a goal to pursuit and a plan to achieve it, being sure that every skill needed to accomplish the selected plan is available in the society.
Because agents' interactions are guided by their information about the others, it is exactly during these interactions that they may detect that this information is either incorrect or incomplete, and eventually revise it.
The last is justified by the fact that a possible reason for an agent to refuse to take part in a coalition is because the sender has a false belief about his capabilities: the sender may believe that the agent can perform an action, when in fact this is not true.

 Professor Ron Sun
Yet another focus is the development of modular reinforcement learning models, in which multiple modules (or agents) compete and cooperate with each other to accomplish tasks, without a priori division of the tasks (i.e., without using any a priori domain-specific knowledge).
This type of reasoning was characterized by a mixture of rule-based and similarity-based processes, exhibiting both rigor and flexibility (as demonstrated in my AIJ paper).
To capture such reasoning, I developed a hybrid connectionist architecture (named CONSYDERR) with both localist and distributed components, that unified rule-based and similarity-based processes and accounted for a variety of CSR patterns.

 AgentLink.org | European Co-ordination Action for Agent-Based Computing
The theory of PRS-like systems has also been widely studied: within the intelligent agents research community, the belief-desire-intention (BDI) model of practical reasoning that underpins PRS is arguably the dominant force in the theoretical foundations of rational agency.
Despite the interest in PRS and BDI agents, no complete attempt has yet been made to precisely specify the behaviour of real PRS systems.
This has led to the development of a range of systems that claim to conform to the PRS model, but which differ from it in many important respects.

 ADMW 2003: Knowledge Representation and the Reasoning Agent :: Background
The Second Augustus De Morgan Workshop dealt with the history of logic, taking the view that there is a historical continuity in trying to logically model the human.
This was in response to the realisation in the AI community, that much of the logic research in ancient and medieval logic was the result of attempts to analyse human (theological) reasoning and was therefore directly potentially relevant to current AI and argumentation problems.
Probability is a major component in common sense reasoning that so far has been developed side-by-side with the new logic.

Slater's argument trades on the notion of contradictoriness in the attempt to show that the negation of paraconsistent logics is merely a subcontrary forming operator and not one which forms contradictories.
Our further goal is to put these logics in the service of practical reasoning systems, since the basic concept of our treatment is that of an agent a reasoning to conclusions using as assumptions the theory of agent b, where a and b may or may not be the same.
Experimental studies conducted in a very difficult area of theorem proving, namely equational reasoning, demonstrate the capacity of the techniques and underline their potential to be a very useful tool for eliminating human interaction requiring expert knowledge.

This paper suggests formal frameworks that can be used as the basis for defining, reasoning about, and verifying properties of agent systems.
We demonstrate that the semantics of Little-JIL are sufficiently well defined to support the application of static dataflow analysis, enabling the verification of critical properties of the agent systems.
This approach is inherently a top-down approach that complements bottom-up approaches to reasoning about system behavior.
