The ability to reason by analogy is essential for many cognitive processes from low-level and high-level perception to categorization. Intuitively, the idea is to use what is already known to explain new observations that appear similar to old knowledge. In a sense, it is opposite of induction, where to explain the observations one comes up with new hypotheses/theories. Therefore, a system capable of both types of reasoning would be superior. In this paper, the authors present an overview of Inductive Logic Programming ILP systems that use reasoning by analogy and discuss the results of combining Analogical Prediction with an ILP system, showing that, for some cases, it is possible to improve significantly the learning speed of the ILP system. This paper will examine the problems that arise in the context of a physically embodied robot that tries to learn regularities in its environment.

通过类比推理的能力对于从低级和高级感知到分类的许多认知过程是必不可少的。直觉上，这个想法是用已知的东西来解释似乎与旧知识相似的新观察结果。在某种意义上，它与归纳法相反，在归纳法中，为了解释观察结果，人们提出了新的假设/理论。因此，能够同时进行这两种推理的系统会更优越。在本文中，作者概述了使用类比推理的归纳逻辑规划ILP系统，并讨论了将类比预测与ILP系统相结合的结果，表明在某些情况下，可以显着提高ILP系统的学习速度。本文将研究在物理具体化的机器人试图学习其环境中的规则的背景下出现的问题。

The Multi Agent System MAS model has been extensively used in different e-commerce tasks. Customer orientation is a crucial component of organizational culture and attention to information about customers' needs should be considered a firm's most basic value. In this paper, the authors evaluate a seller agent's various cognitive parameters, such as capability, trust, and desire. The authors also examine customer orientation value for a pair of buyer and seller agents, such as selecting a seller and buyer agent pair using mental and cognitive parameters, customer orientation value for their mutual benefits, and the competitive negotiation factor. The authors provide a deterministic customer orientation computational model, a competitive negotiation computational model between buyer agent and seller agent, and a logical computational model for selection of the best buyer-seller agent pair. With the help of GUI intermediate, final results are shown.

MAS模型已广泛应用于不同的电子商务任务中。以客户为导向是组织文化的重要组成部分，关注客户需求信息应被视为公司最基本的价值。在本文中，作者评估了卖方代理的各种认知参数，如能力、信任和欲望。作者还考察了一对买卖双方代理的客户导向价值，如使用心理和认知参数选择买卖双方代理对，客户导向价值为他们的共同利益，以及竞争谈判因素。提出了确定性的客户导向计算模型、买方代理和卖方代理之间的竞争性谈判计算模型以及最佳买方-卖方代理对选择的逻辑计算模型。在图形用户界面的辅助下，给出了最终结果。

A mobile ad hoc network MANET represents a system of wireless mobile nodes having random mobility and self-organization into an arbitrary and temporary network, allowing people and devices to seamlessly interact without preexisting communication infrastructure. The lifetime of a MANET depends on the durability of the battery resources of the mobile hosts. Earlier, several routing protocols have been proposed specifically for MANET, but most have not focused on the limitations of battery resources. The failure of these resources severely impacts a communications system during natural disasters and in crucial communication environments. This paper proposes a Mobile Agent MA based link stability aware energy efficient routing protocol that can increase the lifetime of the mobile hosts. A new link cost metric LCM is defined that is used during routing decisions. LCM is a measure of node and path stability. Simulation results indicate that this new link stability aware energy efficient protocol can extend the lifetime of a MANET and can be used in various mission critical applications.

移动自组织网络(MANET)代表了一种无线移动节点系统，该系统具有随机移动性和自组织到任意和临时网络的能力，允许人和设备在没有预先存在的通信基础设施的情况下无缝交互。MANET的寿命取决于移动主机的电池资源的持久性。早些时候，已经提出了一些专门针对MANET的路由协议，但大多数都没有关注电池资源的限制。在自然灾害期间和在关键的通信环境中，这些资源的失效会严重影响通信系统。提出了一种基于移动Agent MA的链路稳定感知节能路由协议，该协议可以提高移动主机的生存期。定义了一个新的链路成本度量LCM，用于路由决策。LCM是节点和路径稳定性的度量。仿真结果表明，这种新的链路稳定感知节能协议可以延长MANET的生命周期，并可用于各种关键任务应用。

Holonic Multi-Agent Systems HMAS provide a convenient and relevant way to analyze, model, and simulate complex systems in which a large number of entities are interacting at different levels of abstraction. Many models have been proposed for the implementation of these systems; however, most are not general enough to cover applications other than the ones for which they are applied. In this paper, the authors introduce HoloJade, an extension to JADE platform, as a generic solution for the development of HMASs in which Holons and their assigned roles are presented as first level entities available at runtime. This includes a detailed description of the extension, in terms of its meta-model, the needed protocols for the possible interactions, and facilities for the reorganization of the holons. In this paper, the authors also present a hypothetical library example to demonstrate the steps for designing a holonic structure using this extension.

全息多智能体系统(HMAS)提供了一种方便和相关的方法来分析、建模和模拟复杂系统，其中大量实体在不同的抽象层次上相互作用。已经提出了许多模型来实现这些系统;但是，大多数都不够通用，无法涵盖它们所应用的应用程序以外的应用程序。在本文中，作者介绍了HoloJade，一个JADE平台的扩展，作为HMASs开发的通用解决方案，其中holon及其分配的角色作为运行时可用的第一级实体呈现。这包括对扩展的详细描述，根据其元模型，可能的交互所需的协议，以及用于重组全息的工具。在本文中，作者还提供了一个假设的库示例来演示使用该扩展设计全息结构的步骤。

In this paper, the authors demonstrate the use of software agents to extend the role of humans in a collaborative work process. The extended roles to agents provide a convenient means for humans to delegate mundane tasks to software agents. The framework employs the FIPA ACL communication protocol which implements communication between agents. An interface for each agent implements the communication between humans and agents. Such interface and the subsequent communication performed by agents and between agents contribute to the achievement of shared goals.

在本文中，作者演示了如何使用软件代理来扩展人类在协作工作过程中的角色。代理的扩展角色为人类将日常任务委托给软件代理提供了一种方便的方法。该框架采用FIPA ACL通信协议实现代理间的通信。每个代理的接口实现人与代理之间的通信。这种接口以及随后由代理和代理之间执行的通信有助于实现共享目标。

The article discusses the sociological background and the general features of a new simulation toolbox, which was explicitly designed to describe, design and simulate multi-agent systems whose component agents are endowed with the capability to exchange norm invocations and to internalize norms, to develop codes of norms and to change them. This toolbox takes into account that normative behavior can only originate in the interpretation of norm invocations and the deliberate decision to abide by the emerging norms-otherwise what emerges is only a transitory regularity. Agents designed with the help of this toolbox are endowed with initial rule sets that they can vary over time, according to the experience gained.

本文讨论了一个新的仿真工具箱的社会学背景和一般特征，该工具箱被明确设计用于描述、设计和模拟多智能体系统，其组成智能体被赋予交换规范调用和内化规范、制定规范代码和更改规范代码的能力。这个工具箱考虑到，规范行为只能起源于对规范调用的解释，以及遵守新出现的规范的深思熟虑的决定——否则，出现的只是一种短暂的规律。在这个工具箱的帮助下设计的代理被赋予了初始规则集，这些规则集可以根据获得的经验随时间变化。

This article discusses the TAXSIM model for the simulation of tax evading behavior in a computational model of a single market sector. The rate of tax evasion is an agreement between an employer and an employee that is made to reduce costs. The agents' expectations and satisfaction are results of the agents' individual learning, based on their own experiences and on those in their social network. This way the emerging social approach to tax evasion feeds back to individual behavior. The series of experiments reported in this chapter analyze scenarios in which 1 the quality of governmental services increases permanently, 2 a market leader unilaterally adopts the legal position, and 3 multi-national companies with tax allowances enter the market. In addition, we show that in this model, the level and efficiency of tax audits alone cannot control and explain the emerging tax compliance level.

本文讨论了在单一市场部门的计算模型中用于模拟逃税行为的TAXSIM模型。逃税率是雇主和雇员之间达成的一项协议，目的是降低成本。agent的期望和满足是agent个体学习的结果，基于他们自己的经验和他们的社会网络中的经验。通过这种方式，新兴的社会逃税方法会反馈到个人行为中。本章报告的一系列实验分析了政府服务质量持续提高，市场领导者单方面采取法律立场，以及跨国公司免税进入市场的情景。此外，我们还表明，在该模型中，仅靠税务审计的水平和效率无法控制和解释新出现的税收合规水平。

Multi-scale modeling of complex biological systems remains a central challenge in the systems biology community. A method of dynamic knowledge representation known as agent-based modeling enables the study of higher level behavior emerging from discrete events performed by individual components. With the advancement of computer technology, agent-based modeling has emerged as an innovative technique to model the complexities of systems biology. In this work, the authors describe SPARK (Simple Platform for Agent-based Representation of Knowledge), a framework for agent-based modeling specifically designed for systems-level biomedical model development. SPARK is a stand-alone application written in Java. It provides a user-friendly interface, and a simple programming language for developing Agent-Based Models (ABMs). SPARK has the following features specialized for modeling biomedical systems: 1) continuous space that can simulate real physical space; 2) flexible agent size and shape that can represent the relative proportions of various cell types; 3) multiple spaces that can concurrently simulate and visualize multiple scales in biomedical models; 4) a convenient graphical user interface. Existing ABMs of diabetic foot ulcers and acute inflammation were implemented in SPARK. Models of identical complexity were run in both NetLogo and SPARK; the SPARK-based models ran two to three times faster.

复杂生物系统的多尺度建模仍然是系统生物学领域的核心挑战。一种称为基于代理的建模的动态知识表示方法可以研究由单个组件执行的离散事件产生的更高级别的行为。随着计算机技术的进步，基于智能体的建模已经成为一种模拟系统生物学复杂性的创新技术。在这项工作中，作者描述了SPARK(基于代理的知识表示简单平台)，这是一个专门为系统级生物医学模型开发设计的基于代理的建模框架。SPARK是一个用Java编写的独立应用程序。它为开发基于代理的模型(ABMs)提供了一个用户友好的界面和一种简单的编程语言。SPARK具有以下特征:1)连续空间，可以模拟真实的物理空间;2)柔性剂的大小和形状，可以代表各种细胞类型的相对比例;3)生物医学模型中可以同时模拟和可视化多个尺度的多个空间;4)方便的图形用户界面。现有糖尿病足溃疡和急性炎症的ABMs在SPARK中实施。在NetLogo和SPARK中运行相同复杂度的模型;基于spark的模型运行速度要快两到三倍。

Norm and Social Compliance: A Computational Study 规范与社会顺从:一项计算研究

The necessity to model the mental ingredients of norm compliance is a controversial issue within the study of norms. So far, the simulation-based study of norm emergence has shown a prevailing tendency to model norm conformity as a thoughtless behavior, emerging from social learning and imitation rather than from specific, norm-related mental representations. In this article, the opposite stance-namely, a view of norms as hybrid, two-faceted phenomena, including a behavioral/social and an internal/mental side-is taken. Such a view is aimed at accounting for the difference between norms, on one hand, and either behavioral regularities conventions on the other. After a brief presentation of a normative agent architecture, the preliminary results of agent-based simulations testing the impact of norm recognition and the role of normative beliefs in the emergence and stabilization of social norms are presented and discussed. We focused our attention on the effects which the use of a cognitive architecture namely a norm recognition module produces on the environment.

在规范研究中，是否有必要对规范遵从的心理成分进行建模是一个有争议的问题。到目前为止，基于模拟的规范出现研究表明，普遍倾向于将规范遵从建模为一种无意识的行为，这种行为来自社会学习和模仿，而不是来自特定的、与规范相关的心理表征。在本文中，采取了相反的立场，即将规范视为混合的，两方面的现象，包括行为/社会和内部/精神方面。这种观点的目的是一方面解释规范和另一方面解释行为规律约定之间的差异。在简要介绍了一个规范的代理架构之后，本文提出并讨论了基于代理的模拟的初步结果，该模拟测试了规范识别的影响以及规范性信念在社会规范的出现和稳定中的作用。我们将注意力集中在使用认知架构即规范识别模块对环境产生的影响上。

Internalizing Norms: A Cognitive Model of (Social) Norms' Internalization 内化规范:(社会)规范内化的认知模型

International journal of agent technologies and systems

Pub Date : 2010-01-01 DOI: 10.4018/jats.2010120105

Internalization is at study in social-behavioural sciences and moral philosophy; lately, the debate was revamped within the rationality approach to the study of cooperation and compliance because internalization is a less costly and more reliable enforcement system than social control. But how does it work? So far, poor attention was paid to mental underpinnings of internalization. This article advocates a rich cognitive model of different types, degrees and factors of internalization. In future work, it will be implemented on a normative agent platform to simulate the individual and social effect of internalization.

内化是社会行为科学和道德哲学的研究热点;最近，由于内部化是一种比社会控制成本更低、更可靠的执行系统，因此在研究合作与服从的理性方法范围内进行了辩论。但它是如何工作的呢?到目前为止，人们对内化的心理基础关注甚少。本文提倡一种具有不同内化类型、程度和因素的丰富认知模式。在未来的工作中，将在规范的代理平台上实施，模拟内化的个体效应和社会效应。
