Programming agents in Jade
(web version) (french version)
Set of source codes for the course/tutorial on multi-agent programming with the JADE platform.
To run these codes, it is necessary to import the library “JadeUPHF.jar”.
This library is an update, with JAVA 25, of the last official version of [Jade]
(https://jade.tilab.com) of Tilab and add functionalities to easier the implementation of agents.
Virtual threads are used to run the agents and their behaviors, which allows to run a large number of agents on a single machine (10000).
The source of this new version, and notes, can be accessed from here : JadeUPHF.
The library is available here : JadeUPHF.jar.
The following codes need, thus, this library and Java >= 25.
NB. if you get this error in your preferred IDE while launching an example :
SEVERE: Communication failure while joining agent platform: No ICP active
The reason is that you have not closed the previous jade instance. Completely stop/close a jade run before launching another one
Basics: Agent, Behavior, and Sending Messages
Agents without behavior or communication
- To test the installation of Jade, the classic HelloWorld
- AgentHello : code for a simple agent displaying a message on the console
- AgentHelloParametre : also code for a simple agent displaying a message on the console, but the message is passed as a parameter
Agents with behaviors
- Add simple behaviors to an agent, examples
- AgentHelloSalut : code for an agent with simple behaviors
- AgentHelloEuropeenSequentiel : code that launches 2 agents that owns behaviors executing in sequential.
- AgentHelloEuropeenParallel : code that launches 2 agents that owns behaviors executing in parallel.
Communicating Agents
- Classic example of a communication test between 2 agents: ping-pong
- pingPong: Code that launches two agents that communicate with each other. The ping agent sends a ball to the pong agent which returns it to ping which in turn returns it, …
- AgentPingPlouf: code for an agent that sends a random message and waits for a response..! This will come from the white pages agent (AMS) telling him that there is no one at the address indicated…
- Example with message filtering:
- ticTac : an agent sends messages tagged with 2 different types; an agent receives them and treats them differently according to their types.
Interactive agents
- Use of a small graphical interface to facilitate dialogue with the user
Service Management
- helloWorldService : Codes for agents each linked to a window. These agents discover each other by searching for services and send each other simple messages
- serviceDetection : Some agents register to the yellow pages (DF) for a given service; little by little. Another agent has subscribed to (DF) to be notified when an agent registers or unsubscribes from this service.
Agents with FSM behaviors
- Agents that have behaviors organized according to a finite state machine (FSM) : fsm.
Two examples are given :
- salutations : sequences of behavior for European greetings within an agent,
- review : process of submitting and reviewing an article between an author agent, a journal agent and three reviewer agents
Interaction protocols
- Requests : codes for communication of requests using the AchieveRE protocol.
- English Auction: codes using the communication protocol ContractNet to simulate a sealed english auction (1 round).
- Vote Borda : codes illustrating communication between agents by the ContractNet protocol for vote by Borda count.
- Vote Borda 5000 : codes illustrating communication between agents by the ContractNet protocol for vote by Borda count, for 5000 agents.
- Vote DoubleBorda : codes illustrating communication between agents by the ContractNet protocol for vote by using Borda count twice if needed. <!—
- Vote Condorcet : codes illustrant la communication entre agents par le protocole ContractNet pour un vote de Condorcet augmenté pour être effectué en 1 tour.
- Negociation : codes à compléter pour coder la négociation 1-1.
Exemple complet, support à développements :
- agentsVoyage : codes pour des agents simulant des agences de voyages —
