Multiagent systems are increasingly becoming popular among researchers spanning multiple fields of study. However, existing studies only models communication interaction between agents as either fixed or switching topologies described by crisp graphs supported by algebraic graph theories. In this paper, we propose an alternative approach to describing agent interactions using fuzzy graphs. Our approach is aimed at opening up new research avenues and defining new problems in coordination control especially in terms of dynamics between agents’ states, graph topologies and coordination objectives. This paper studies distributed coordination on fuzzy graphs where the edge-weights modeling network topologies are dependent on the states of the agents in the network. In hindsight, the network weights are adjustable based on the situational state of the agents. First, we introduce the concept of fuzzy graphs and give some distinguishing features from the crisp or fixed graphs. Next, we provide some membership functions to define the state-dependent weights and finally we use some simulations to demonstrate the convergence of the proposed consensus algorithms especially for cases where the agents are subject to system failures.  相似文献

Background: This study investigates the role of figures of speech in the process of conceptual change in the physics classroom. Purpose: Its objectives are to examine what teachers and students perceive to be the advantages in using figures of speech in teaching physics concepts, what they perceive to be the challenges in using them, and how teachers use these in their classrooms to minimize the challenges faced. Sample We chose a purposive sample of 95 students and nine teachers of physics, in four schools in Lebanon. Design and methods: A mixed-method approach was used. Interviews were conducted with physics teachers; questionnaires were distributed to students, and non-participant classroom observations were carried out. Results: Teachers viewed figures of speech as a tool that helps them transmit abstract physics concepts to students in a simpler and concrete way. Questionnaires and non-participant observations revealed several examples of figures of speech used and the positive responses of students towards them. Conclusions: The study suggests several ways to overcome the drawbacks. This study highlights the urgent need for all stakeholders to work collaboratively to include figures of speech in the curriculum to enhance the process of conceptual change in the physics classroom.  相似文献
