Dear all,

Is it possible to have more sources for customising the Jason Architecture?

Thank you.

Best regards.

Re: [Jason-users] Create a timer based on seconds in Cartago

[Burak K. <bbu...@gm...>]

Hi Jomi,

When I pause the agent execution on the container, everything stops, but
another thread which created using a session does not stop. I would like to
capture the "Pause" of the agents runtime to pause the other thread.  But i
think your idea is also applicable.

Thank you.

Best regards.

Re: [Jason-users] Create a timer based on seconds in Cartago

[Jomi H. <jom...@gm...>]

Hi Burak,

I am not sure what do you mean for “pausing” an artifact. If it is related to some “wait” operation of cartago, I do not know a way to get that state. You likely have to handle that state by yourself and send that information to your other thread. 

HTH,

Jomi

Re: [Jason-users] Create a timer based on seconds in Cartago

[Burak K. <bbu...@gm...>]

Hi all,

Is it possible to detect the "Pause" operation of the Jason & Cartago
container, because I would like to stop my extra thread-controlled timer
when the container is paused? Is there any operation for this?


Thank you for your help.

Best regards.

Hi Jomi,

I had solved my problem as you suggested. Thank you so much for your help.
I share the solution I hope it can help others in the future.



* this.beginExternalSession(); commit(); this.endExternalSession(false);*

However, I have another question, I have a function which is encapsulated
inside an artefact namely getUDPMessage(). However, this should be
continuously checked in case of data is sent anytime. Is it possible to
attach a feature for continuously listening a function of an artifact?

Best regards.

Re: [Jason-users] Create a timer based on seconds in Cartago

[Jomi H. <jom...@gm...>]

Hi Burak,

I guess that instructions that change the state of the artifact (obs props/signals) have to be executed in a special way in cartago to avoid breaking its atomicity/transactional features. 

if a thread of yours is changing the artifact, the change should be executed inside a block beginExternalSession/endExternalSession. In your code, the thread is created inside this block, but the signal is not running inside such a block. Maybe you can move the begin/end… to inside the “run()” method.

Re: [Jason-users] Create a timer based on seconds in Cartago

[Burak K. <bbu...@gm...>]

Dear all,

I think I solved the problem using the following option :

 this.beginExternalSession();
commit();
this.endExternalSession(false);

I will try it again in the morning. I hope the solution can help the others.

Best regards.

Re: [Jason-users] Create a timer based on seconds in Cartago

[Burak K. <bbu...@gm...>]

Hi,

I deleted the signal and decided to move on with belief addition. However,
it only updates the value from 0 to 1 once. I think as the operation still
goes on because of timerTask, it does not update the observable property.
In the book, I saw that commitObsState was proposed, but I haven't been
able to see any detailed example of usage. Also, I have only seen
commitChanges() in the version that I use.

Best regards.

[Jason-users] Create a timer based on seconds in Cartago

[Burak K. <bbu...@gm...>]

Dear all,

I am trying to create a timer that counts based on seconds. However, I am
getting this error;








*java.lang.IllegalMonitorStateException at
java.base/java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.signalAll(AbstractQueuedSynchronizer.java:1487)
at cartago.Artifact.commitObsStateChangesAndSignal(Artifact.java:573)at

example_JaCaMo.MyTimer.access$000(MyTimer.java:11) at

java.base/java.util.TimerThread.mainLoop(Timer.java:556) at
java.base/java.util.TimerThread.run(Timer.java:506)*

My code is simply like this:





























*public class MyTimer extends Artifact { void init() {
defineObsProperty("mytimer", 0); timer_creation(); } void timer_creation()
{   this.beginExternalSession(); Timer timer = new Timer(); TimerTask task
= new TimerTask(){    private int i = 0;    public void run(){        if (i
<= 30) {        signal("timerEnd");        System.out.println(i);
      }    }}; timer.scheduleAtFixedRate(task, 0, 1000); //1000ms = 1sec
this.endExternalSession(true); }}*

How can I tackle this problem?

Thank you.

Best regards.

Re: [Jason-users] Intention could not finish error

[Jomi H. <jom...@gm...>]

Hi Burak,

I still do not fully understand your application (and its problem).

Anyway, the instruction

	-color(_,ID)[source(_)]

could be revised. If color/2 is perceived, it usually does not work to remove it from the BB because in the next cycle the agent will perceive it again and the belief will be reintroduced. Belief with [source(percept)] reflect the environment, and thus they are not directly manipulated by the agent. The agent can, of course, *act* on the environment so to change it and then, as consequence, perceive something different. 

If the case where color/2 comes from communication (as in the app you sent), the receiver can remove the belief and it remains “removed”. However, I think that belief told by other agent should preferably be removed by them (using untell performative).

The best practice is that the agent changes only beliefs it has included, which have [source(self)] — what we sometimes call “mental notes”. 

However, I am not sure if this issue is related to the problem we are facing with a different environment. 

HTH,

Jomi

Therefore, the next contextual change happens right after the completion of the previous event. The planning mechanism is simple, various consecutive products which have IDs keep coming and the agent is trying to match these products according to their colours. It also uses IDs for comparison because agents run so fast to generate the same event (i.e same products with the same IDs).

For example product red with ID 0 is generated, then product blue with ID 1 can be generated after 2 minutes or hours. Is it possible to define a timeout for the intention? Or is it possible to await it forever etc?

Re: [Jason-users] Intention could not finish error

[Rafael H B. <r.b...@ac...>]

Hi Burak,

As far as I'm aware there is no implicit timeout for intentions. There
could be and error in the actions that the intention execute, and I'm not
sure if a failure to delete a belief also causes the intention to abort.
This is very likely to happened because you manually deleting beliefs that
are being created from perception (if I understood correctly) without
making the plan atomic. Also, if you want a plan to trigger due to a belief
addition, it should start
+color(...
And not
+!color

Re: [Jason-users] Intention could not finish error

[Burak K. <bbu...@gm...>]

Hi Jomi,

Thank you for your reply. Let me summarize the story for you,

*+!color(red,ID) : color(red,ID2) .....*

For example, a sensor reads the colours of the incoming bricks. The first
brick is red and has the ID 0, then this creates a belief addition as the
head of the plan shows. { *+!color(red,ID)  *}.

Then, the second brick comes after 5 minutes, which is red and id is 1.

In this case, this context matching should be triggered {*+!color(red,ID) :
color(red,ID2) & (ID-ID2)<2 & not ID == ID2}*

However, until the arrival of the second red brick, I think an implicit timeout
mechanism is self-triggered and kills the intention by giving ''the
intention could not finish error''. If that timeout was disabled, then it
could work and wait until the occurrence of the next event.

Maybe a blind commitment pattern is suitable. But, for this kind of work, I
should be able to disable this timeout easily.  I think I have already
tried .wait commands.

The intention should not be frozen, but patient enough for the next events.
This code works on the computer without any environment, but when I deploy
the code onto a system of course physical events do not happen that often.

Best regards.

Re: [Jason-users] Intention could not finish error

[Jomi H. <jom...@gm...>]

Dear Burak,

I wasn’t able to figure out the error that is happening. Is there something more in the error message? (Besides intention could not finish)

Anyway, any intention can be suspended and resumed latter. The .wait internal action can be used for that, but also .suspend and .resume. 

Maybe the idea of commitments can also help you:

[Jason-users] Intention could not finish error

[Burak K. <bbu...@gm...>]

Dear all,

I have an agent code which is as follows:










*+!color(red,ID) : color(red,ID2) & (ID-ID2)<2 & not ID == ID2  <-
push(ID,ID2); mediumPress; .print("A"); .print("Pushing:",red," ",red);
-color(_,ID)[source(_)];  -color(_,ID2)[source(_)].+!color(red,ID) :
color(_,ID2) & (ID-ID2)<2  & not ID == ID2 <- reject(ID2); ejectProduct;
.print("B"); -color(_,ID2)[source(_)].+!color(OC,ID) : color(red,ID2) &
(ID-ID2)<2 & not ID == ID2<- push(ID,ID2);.print("C"); mediumPress;
.print("Pushing:",OC," ",red); -color(_,ID)[source(_)];
 -color(_,ID2)[source(_)].+!color(OC,ID) : color(OC,ID2) & (ID-ID2)<2 & not
ID == ID2 <- push(ID,ID2);.print("D"); mediumPress; .print("Pushing:",OC,"
",OC); -color(_,ID)[source(_)];  -color(_,ID2)[source(_)].+!color(OC,ID) :
color(OC2,ID2) & not OC==OC2 &  (ID-ID2)<2 & not ID == ID2 <-  .print("E");
 reject(ID2); ejectProduct;    -color(_,ID2)[source(_)].*

The code runs well with a textual environment because the occurrence of the
events is quite frequent. Therefore, the next contextual change happens
right after the completion of the previous event. The planning mechanism is
simple, various consecutive products which have IDs keep coming and the
agent is trying to match these products according to their colours. It also
uses IDs for comparison because agents run so fast to generate the same
event (i.e same products with the same IDs).

However, when I deploy this code to a physical system I get an "Intention
could not finish" error, the occurrence of events can have long time
periods because of the physical environment. For example product red with
ID 0 is generated, then product blue with ID 1 can be generated after 2
minutes or hours. Is it possible to define a timeout for the intention? Or
is it possible to await it forever etc?

Best regards.

Re: [Jason-users] What is the best way/problem to show the power of Jason/BDI compared to Jade?

[Rafael H B. <r.b...@ac...>]

Hi Burak,

Nothing that is computable is impossible in either, but it must be the case
that some applications are easier to do in one than the other, as you
conjectured, but it isn't easy to show that. Certainly an essentially
reactive application like this will not help so much to differentiate the
two. You'd have to think one where agents have long courses of action to
achieve a goal, which depends on subgoals for which the courses of action
may be more appropriate or fail depending on the context (the state of the
environment and other agents). Perhaps Jomi has some pointers in the
literature that tried to do this, I don't remember from the top of my mind
now. Well, perhaps you could try the codes for the past multi agent
programming competitions, the ones from my group and Jomi's are publicly
available.

[Jason-users] What is the best way/problem to show the power of Jason/BDI compared to Jade?

[Burak K. <bbu...@gm...>]

Dear all,

I have been researching for this answer for 2-3 weeks. I have a case study
that accepts four different coloured bricks. The system can eject any brick
outside of the system and can merge two bricks. The functionality of the
system works in this manner. It reads the colour of the brick and decides
whether to accept it or eject it. It then accepts a second brick and gives
the same decision. Then two bricks are merged and ejected. The two combined
bricks may have the same colour or maybe different.

Therefore, considering such a system, evolving this to what kind of problem
may hinder the power of BDI while it becomes very hard or impossible with
Jade?

Thank you.
Best regards.

Re: [Jason-users] Is it possible to establish messaging between two centeralized containers?

[Jomi H. <jom...@gm...>]

Hi Burak,

the use of Jade depends on several aspects…. 

just to start, have you checked
1) the FAQ 
	http://jason.sourceforge.net/doc/faq.html#_how_to_run_my_agents_on_several_machines_with_jade
2) the demo 
	https://github.com/jason-lang/jason/tree/master/demos/distributed-jade/case1

does the demo run on your machines?

HTH

Jomi

ps.: you are right, Jason creates the containers.

Re: [Jason-users] Is it possible to establish messaging between two centeralized containers?

Dear All,

I switched to Jade infrastructure. There are two -jar files that were built
to run inside two computers (they are in the same LAN). However, Computer A
cannot send messages to computer B and vice-versa.

I tried infrastructure: Jade for both -jar files first ( agents
successfully sent messages to each other in the
centralized infrastructure). Then I tried infrastructure:
Jade(main_container_host("IP address of computer A ")) for two jar files.

However, they cannot send messages to each other. BTW, I have not created
any Jade container I assume that Jason already handles it by itself once
infrastructure: Jade is instructed.

[Jason-users] How to clear all combination of a percept?

[Burak K. <bbu...@gm...>]

Dear all,

I have to clear a specific percept of a specific agent.

I used the following code to clear its two combinations.

removePercept("dropAgent",Literal.parseLiteral("dropButtonStatus(true)"));
removePercept("dropAgent",Literal.parseLiteral("dropButtonStatus(false)"));

It is worked, but for each combination of dropButtonStatus() or for any
type of percept, I have to input the parameters one-by-one.

I also tried something like this to address and clear all percepts related
with dropButtonStatus
removePercept("dropAgent",Literal.parseLiteral("dropButtonStatus(_)"));

However, it did not work. How can I do it?

Thank you.
Best regards.
