1 MaSMT A Multi-agent System development framework by Budditha Hettige Department of Computer Science

2 MaSMT MaSMT is a java based multi-agent system development framework Especially designed for development of English to Sinhala machine translation system Also capable to develop any multi-agent based system through its architecture is a lightweight Java library for designing and simulating Multi-Agent Systems is free software licensed under the GNU GPL featuring Download 2

4 MaSMT Agent is a simple Java Thread (Abstract class) that can be used as an agent of the Multi-agent system 2 Message Queue Abstract Agent information Group Rule Id Action/Task Ontology Manage by a specific manager Introduction to Agent Technology 4

5 MaSMT- Agent Model Model is based on three core concepts: agent, group and role 5

10 Sections Activate section which contains some code to be executed when an agent is created. Live section which contains the main code of the agent. Generally, this section is made of a (quasi) infinite loop describing the behavior of the agent. End section which contains some code which is executed when an agent is terminating (either because it finishes its behavior or because it is killed). 10

20 MaSMT Manager A manager agent consists of number of ordinary agents within its control. Manager agents can directly communicate with other manager agents and each Every ordinary agent in the swarm is assigned to a particular manager agent Type MaSMTManager MaSMTGUIManage Introduction to Agent Technology 20
