Jason is an Open Source interpreter for an extended version
of Agent Speak – a logic-based agent-oriented programming
language – written in Java(TM). It enables users to build
complex multi-agent systems that are capable of operating in
environments previously considered too unpredictable for computers
to handle. Jason is easily customisable and is suitable for
the implementation of reactive planning systems according to the
Belief-Desire-Intention (BDI) architecture.
Programming Multi-Agent Systems in Agent Speak using
Jason provides a brief introduction to multi-agent systems
and the BDI agent architecture on which Agent Speak is based. The
authors explain Jason’s Agent Speak variant and provide
a comprehensive, practical guide to using Jason to program
multi-agent systems. Some of the examples include diagrams
generated using an agent-oriented software engineering methodology
particularly suited for implementation using BDI-based programming
languages. The authors also give guidance on good programming style
with Agent Speak.
Programming Multi-Agent Systems in Agent Speak using
Jason
* Describes and explains in detail the Agent Speak extension
interpreted by Jason and shows how to create multi-agent systems
using the Jason platform.
* Reinforces learning with examples, problems, and
illustrations.
* Includes two case studies which demonstrate the use of
Jason in practice.
* Features an accompanying website that provides further learning
resources including sample code, exercises, and slides
This essential guide to Agent Speak and Jason will be
invaluable to senior undergraduate and postgraduate students
studying multi-agent systems. The book will also be of interest to
software engineers, designers, developers, and programmers
interested in multi-agent systems.
