Some plan recognition approaches represent knowledge about the agents under observation in form of a library. Although such use conceptually similar library representations, they seldom, if ever, exact same domain order to directly compare their performance. For any non-trivial domain, libraries have complex structures representing possible agent behavior, so often fail be tested at limits and only rarely are compared with each other experimentally, leading need for principled approach...

The demand for systems incorporating artificial intelligence, such as multi-agent systems, is continually increasing. Simultaneously, there a growing need developing tools to support this field, ensuring better fault tolerance within projects. This particularly crucial given that these possess characteristics render them non-deterministic, thereby amplifying the challenge of conducting tests. To address challenge, mapping tool has been developed. automatically generates graphical model,...

Knowledge transfer enables the development of complex multi-agent systems featuring agents that share knowledge to execute tasks. Environments shaped by involve assuming specific roles, reasoning about environment and other agents, forming organizations through well-defined plans strategies. This paper presents an organizational model for transfer, introducing a centralizing role, named organizer, responsible managing relations between system, their roles. An interaction protocol is...

Most approaches to plan recognition are based on manually constructed rules, where the knowledge base is represented as a library for recognising plans. For non-trivial domains, such libraries have complex structures representing possible agent behaviour achieve plan. Existing seldom tested at their limits, and, though they use conceptually similar representations, rarely exact same domain in order directly compare performance, leading need principled approach evaluating them. Thus, we...
