jason-users Mailing List for jason

Hi Bourdil, you are right in your analysis of the problem. I am working on a solution for that — that is in the java level, not .asl. 

I hope to come back soon with a solution. 

Best,

Jomi

ps.: Indeed, the block() is executed after the answer from the environment is received… So I do not know why the agent is being waked … I guess previous versions of JADE worked differently (the versions we used to develop the JADE infrastructure)…. Again, I need to investigate it further.

I investigated the problem I had, relative to a 100% cpu consumption when executing the example from http://www.emse.fr/~boissier/enseignement/maop11/doc/jason-api/mini-tutorial/jason-jade/index.html
To sum up, the seller agent (ie:JadeAgArch)  never sleep.

I understood that :


1)      In class JasonTSReasonner (method action), a jade Cyclic behavior, and in async mode (the default), the agent try to sleep 1sec after each reasonning cycle . This is implemented through a call to jade.core.Behaviour.block.

2)      Nevertheless, it asks for percept to environnementAID at each perceive phase of a reasoning cycle : QUERY_REF acl message with content getPercept

3)      EnvironmentAID  answer (an INFORM ACL message), thus waking up the agent . The documentation of Jade's block clearly state that block is in fact non blocking. (http://jade.tilab.com/doc/api/jade/core/behaviours/Behaviour.html#block())

4)      Hence, the agent never sleep and consume 100% CPU.


Am I right ?
If yes, Is there a way  to  change that behavior   ? If not , how can I avoid these , maybe by allowing to put some wait from the asl sources ?

Hi Alejandro,
You mean like this :
[cid:image001.png@01D2BE6B.D9314A70]

If yes, it did not solve my problem. Note I have update Jason config to point to the jasonbookTrading\lib\jade.jar lib, with no success.

Objet : Re: [Jason-users] Problem with eclipse integration of jason/jade

Hi Pierre,

I had  a similar problem with cartago. It seems that eclipse doesn’t find the referenced libraries when added directly while configuring the class path of the project. I solved the issue by creating a folder lib in my project and putting there a copy of the jade.jar file (and other jars equal); Then, adding this copy of jade.jar to the referenced libraries.  Solved.

Best regards

Hi,

I’m trying to run the jade integration example in eclipse (neon.3, java1.8_111, Ubuntu  16.04) .

It seems my build path is correct (include the jade lib from the JADE distribution, in accordance with Jason configuration). Nevertheless, when I run the Jason project, I got a ClessDefNoitFound  : JadeAgArch



[cid:image008.jpg@01D2BE6B.D9314A70]


Is there any way to make it run within eclipse ?

Thanks by advance

Following http://jason.sourceforge.net/mini-tutorial/jason-jade/ , with jedit and jade.lib from jade distribution.



Once I run the system, and sniff john agent with jade sniffer, I observe a very fast growing sequence of  message with the following form :

INFORM : From other to john

QUERY-Ref : from john to other.



By the way, this take 100% of my CPU.  This seems weird as john is a seller  and I expect him to wait, doing nothing, for a buyer to send a CFP



The Jason/jade seller's behavior is completely different than the same  example ran using jade only.  In the latter , things seems ok (exchange are sparses , as expected).



Behavior in pure JADE :

Behavior in JASON/JADE

[cid:image002.png@01D2BDE3.C38BA360]









Is this normal, or did I miss something ?

Hi Andres,

the simplest way is to use the internal action .stopMAS. When some agent detects the termination condition, it executes this action. For instance, in the case of time elapsed:

!stop.

+!stop <- .wait(10000); // wait for 10 seconds
                 .stopMAS.

HTH,

Jomi

My project consists of 12 agents who perform specific tasks (each one has its own plans) and I need to stop the execution when a time limit is reached or a certain number of movements are fulfilled. I have read the example "gold minners II", but I don't understand the way they stop the execution here. How can I stop the system when the conditions are met?. I appreciate your help.
