Re: [Repast-developer] Multiple Monitors causes Win XP Machine Reboot

[Nick C. <nic...@gm...>]

Chryanthie,

This is very odd. All the repast developers have dual monitors and  
repast j runs fine for us under WinXP. This may be a driver issue for  
your machines or something.

[Repast-developer] Multiple Monitors causes Win XP Machine Reboot

[Chamis, C. D <chr...@bo...>]

Multiple Monitors causes Win XP Machine Reboot
We tried to run Repast J (both our app and a Repast exmaple demo) on a
windows XP system with two moniotrs (display hardware units) and we get
the Blue Screen of Death.

Who is the best person to contact about fixing this bug.  We think it is
a matter of inserting a command to select a HW display/monotor if
mulitple HW displays are available.

If at a minimum someone will direct us to the files that need to be
examined to resolve this issue, we woul greatly appreciate the
assistance.

If there is already an option to handle this in the code, please direct
us to the approriate class and method.

Thank you!

[Repast-developer] RepastJ: Two VectorDisplays possible?

[Pimin K. K. <spa...@gm...>]

Dear All,

I have to types of objects that i want to visualize in RepastJ 3.
object A (human agent) implements Drawable, the object B (road
segment)implements NonGridDrawable.

To visualize objects A, I use a Multi2DGrid/MultiObject2DDisplay combo,
To visualize objects B, I have used a VectorSpace/VectorDisplay combo.

My problem is 1) getX() for Drawable is in grid coordinates, while
getX() for NonGridDrawable is in screen coordinates. What I would like
is objects A and B to be displayed on top of each other (each have
geo-coordinates that a "in sync").

I have a running temp solution that uses a RasterSpace/Value2DDisplay
to display the roads in a cellular fashion, but this gives a lo-res
image of the road-segments, and is obviously not what i want.

Question 1: Would you recommend using something like the
OpenMapDisplay, and reimplementing the agents?

Question 2: Would you recommend that I implement a custom space for my agents?

Question 3: I HAVE tried using a vector space for both the agents and
the roads(both implementing NonGridDrawable), but for some reason my
Repast will only displays the roads, and not the agents. Should this
approach be possible, or is it just not possible to use two
VectorDisplays?

Any suggestions would be much appreciated.

By the way, running repast simulations on the web with Java Web Start
is really cool. I've made a small testcase at

Summary: NetworkFactory, NetUtilities Random initialization needed

Initial Comment:
NetworkFactory, NetUtilities Random initialization needed

Several methods in
uchicago.src.sim.network.NetworkFactory make calls to
uchicago.src.sim.network.NetUtilities.randomRewire or
uchicago.src.sim.network.NetUtilities.randomRewireSymmetric.

These NetUtilities methods use
uchicago.src.sim.util.Random to generate random
numbers. For example, NetUtilities.randomRewire calls
Random.uniform.nextDoubleFromTo.

The documentation for uchicago.src.sim.util.Random
states:

  "Before using any of the instance variable
  distributions, these distributions must be created
  via the appropriate create* method."

However, the instance variable distributions don't seem
to be intialized within the NetUtilities class for use
by its static methods.

This means that if one calls certain NetworkFactory
methods such as createWattsStrogatzNetwork (as I did)
without first manually creating
uchicago.src.sim.util.Random.uniform, then one gets a
strange, very difficult to track down
NullPointerException when NetUtilities.randomRewire
calls Random.uniform.nextDoubleFromTo and finds no
Random.uniform object (see line 726 of NetUtilities).

The workaround, of course, is to manually create the
required distribution in user code using, e.g.,
uchicago.src.sim.util.Random.createUniform().

Neither the origin this strange Exception nor the need
to manually create the distribution are documented in
the NetworkFactory or NetUtilities classes.

I'm filing a bug in part as documentation of this
issue, hopefully to save others some time in tracking
this down and working around it.

[Repast-developer] Help with Repast S!!!!

[Luis R. <luc...@gm...>]

 Hello,

I installed repast_simphony_alpha.1 and added it to eclipse.

I used the repast simphony tutorial to creat the agent and context creator
class stabs.

Then, i launch repast GUI to create the scenario, but, when i tried to
execute the model, with visualization(2D, 3D and chart visualization), after
following each step in the tutorial, nothing happens.

Can someone help me to resolve this problem, please???

Re: [Repast-developer] getTickCount/getCurrentTime - why typed asdoubles?

[North, M. <no...@an...>]

This is a good question.  Users can schedule events with real numbered
values.  This is useful for modeling processes with known or
approximately known physical timing (e.g., modeling the arrival of

[Repast-developer] getTickCount/getCurrentTime - why typed as doubles?

[Les G. <ga...@ui...>]

I'm implementing some extensions to Repast.
Regarding uchicago.src.sim.engine:

The TickCounter interface specifies the method "getTickCount" which
returns a double.  The SimModel class specifies the method
"getCurrentTime" which also returns a double.

Question:

  Both these methods refer to simulation ticks or times. Why
  are their return types specified as "double", which is a floating
  point type, and not int or long? When would a RePast-computed tick or
  time count ever be fractional, i.e., anything but an integer?

  (If I've got this right, the method of updating sim ticks is through
  reading "nextTime" fields in BasicAction.java; BasicActions are
  placed in a priority queue called ActionQueue (nb: Java 1.5 now has
  java.util.PriorityQueue). Sim time is advanced to the minimum time
  (next) entry in this queue - so it can leap forward by more than one
  tick depending on the times for which the BasicActions were
  (re)inserted in the ActionQueue. Nonetheless, all the time specifiers
  I could find in the RePast code are integer values, typically 0 or 1,
  and it's hard to envision when a float would be needed for a
  simtick.)

Suggestion:

  While the inheritance and implementation graphs for these interfaces
  are clearly different, both methods seem to be intending to return
  the current simulation tick or time. Why the difference in names
  then?  It seems like it might be a good idea to unify the concept of
  getting access to the current simulation time/tick, unless there
  really is some underlying conceptual difference that I'm not seeing.

Thanks,

Re: [Repast-developer] Getting rid of warnings? Also Repast S javadoc?

[Miles P. <mil...@gm...>]

Oh and not to be defensive, but to amplify the point about generics  
below, I am sure you understand that there is a significant amount of  
new work here including exploration of various levels of  
abstraction...it seems to me that the team has put a lot of effort  
into that, and that iun terms of code quality (which I think will be  
very high, if I do say so for others if not myself) the important  
thing right now is to get the basic abstractions and collaborations  
right -- we will only have one chance to do some of this stuff right  
--  but as the apis are not near been frozen in the current release  
(the score stuff in particular should be regarded as exploratory/ 
pilot level) it sometimes isn't efficient to sort through the various  
fiddly bits about generics -- the case you note below being a simple  
example, but when one find oneself looking at stuff like

		List<Pair<Method, Watch>> list = watchMap.get(className);
		if (list == null) {
			list = new ArrayList<Pair<Method, Watch>>();
			watchMap.put(className, list);
		}
		list.add(new Pair<Method, Watch>(method, watch));


	protected <X> Iterable<X> getContextFilter(Context<? extends X>  
context,
	                                           Predicate<X> filter) {
		return new IterableAdaptor<X>(new FilterIterator(context.iterator 
(), filter));
	}

certainly not the most involved examples -- one begins to wonder  
wether generics are on balance worth it..I suppose we've decided more  
or less that they are, but may be backing off of some of it a bit.  
Feedback most welcome but again prob. too early in the present  
release for you to have a strong sense of where we are headed w/ some  
low-level implementation details.

Re: [Repast-developer] Getting rid of warnings? Also Repast S javadoc?

[Miles P. <mil...@gm...>]

Hi Pimin,

A bit tongue in cheek, but perhaps you should simply set your  
generics warnings to "ignore"-- that's what I've done which I'm sure  
gives you enormous confidence in our code quality. ;) Seriously,  
leaving aside the issues involved in maintaining Java implementation  
of generics, remember that what is our there is early alpha. I am  
sure we will make a pass through all the warnings as we approach our  
release candidate -- we will also certainly do some major QA work,  
including increasing unit testing coverage, providing more automated  
builds, untangling remaining code and plugin dependencies,  
significant refactorings and so on...whew!

best,

Miles

[Repast-developer] oops, found the Repast S Api :-S

[Pimin K. K. <spa...@gm...>]

Guess looking in the "docs" directory helps :-D
Keep up the good work.

[Repast-developer] Getting rid of warnings? Also Repast S javadoc?

[Pimin K. K. <spa...@gm...>]

Hi developers,

This might not have top priority, but couldn't we get rid of some of
the many warnings that are generated by the current code?

And example is the following source-code:


package repast.context;
public class DefaultContextFactory<T> implements ContextFactory<T> {
...
 public Context<T> createContext(Object contextId) {
  // why not: return new DefaultContext<T>(contextId); ?
  return new DefaultContext(contextId);
 }
}

Could we not include the type-parameter and remove some of the "noise"
from the compiling process.

Also I can't find a javadoc for Repast S, has one not been made?




Best regards,

[Repast-developer] Agents - Blogs

[perez <ms...@ne...>]

Hi,
I have a problem about a project. My organization supplies blogs for free
for their clients. The blogs are hosted in the client's sites. The blogs
themes are chosen by the clients. 1=C2=BA part of the problem - my organiza=
tion
wants to build a page with a link (with description of the post) to the las=
t
post of each one of the blogs. 2=C2=BA - It should appear in the first plac=
e the
links to the most popular blogs, i.e., the blogs with more posts.
This is a simplified way to describe the problem. There will be other
metrics to know for instance, how long a post stays in our site, etc.
The architecture should be .net.
Which is the approach you suggest? (software agents,...)???????????
Thanks for all the help you can give (ideas, tutorials, etc).

[Repast-developer] Hi

[Mirko G. <gri...@gm...>]

Hi, how are you?
I have a problem. I have two BasicAction into my buildSchedule function.
The first BasicAction is called AgentStep() and in this function
I make this:

*

for* (*int* i=0; i<dipLiberi.size(); i++){

agent = dipLiberi.get(i);

Into this function I assign an agent to an action, who have a duration.
I must called the second BasicAction when I have create the new match
agent-action. I must pass to this second BasicAction the duration of
the action. I try to write this code:
schedule.scheduleActionAt(1, new Action(int x), duration);

but this don't make start the second BasicAction... Can you help me?
Please...


This is all my code of BuildSchedule

*

public* *void* buildSchedule(){

System.*out*.println("Running BuildSchedule");
*

class* EseguiAzione *extends* BasicAction{
*

public* *void* execute(){

....

}

};
*

class* DipendentiStep *extends* BasicAction{
*

public* *void* execute(){

...

schedule.scheduleActionAt(1, *new* EseguiAzione(az,agent), d);

}

};

schedule.scheduleActionAtInterval (1, *new* DipendentiStep());

}



Please help me!!!

Thank you very much

Bye

[Repast-developer] IllegalArgumentException: max <= min

[pchacin <pc...@ac...>]

Greetings

I'm experiencing a very frustrating problem when creating a Histogram in
RepastJ 3.0. From time to time, I get this exception:
Exception in thread "Thread-4" java.lang.IllegalArgumentException: max <=
min
	at hep.aida.ref.FixedAxis.<init>(Unknown Source)
	at hep.aida.ref.Histogram1D.<init>(Unknown Source)
	at
uchicago.src.sim.analysis.HistogramItem.getBinValues(HistogramItem.java:215)
	at
uchicago.src.sim.analysis.OpenHistogramStat.record(OpenHistogramStat.java:190)
	at uchicago.src.sim.analysis.OpenHistogram.step(OpenHistogram.java:293)
	at simrealms.views.histograms.HistogramView.refresh(HistogramView.java:98)

The way I'm creating the histogram is hard to show because I created a
simulation framework that wraps the Repast classses. However, I'm pretty
sure that the values in the histogram are in the range 0.0 1.0. and I
created it with these values as lower and upper bound, respectly. 

However, in some circunstances the max and minimum could be the same (both 0
or both 1) and therefore the condition max <= min could become true. 

If this is the reason, I found this behavor annoying, because there is no 
reason why the histogram could have a 100% of items  with the same value.

I'll appreciate any help regarding this issue. Thanks is advance.

Pablo

[Repast-developer] Problem...

[Mirko G. <gri...@gm...>]

 Hi,
I'am a student of Udine University (Italy). I'm working in my
engeneering-thesis. In particolar
I use REPAST for simulation a warehouse. I have some problem with the time.
In our tutorial I have know that all the actions must be contain in the
*public void buildSchedule() *function and the step will be defined in the
*public void step()* function into the agent class, true? The problem is
that in my
project I have more action with a different "action-time". For example the
picking time
and the replenishment time are different in the werehouse. I don't know
organize my project.
Can you send me an example where the action are more the one and the
"action-time" is different?

Thank you very much...
Bye
Mirko

Re: [Repast-developer] [Repast-interest] (no subject)

[Nick C. <nic...@ve...>]

Michel,
 
Re. direct communication, each agent has access to the context (think a Java
collection in this case) in which all the agents reside. Using that you can
get a reference to each agent from every other agent. Alternatively, you
could have a class that handles all the interagent negotiation. Note that
this latter is not the "environment" but rather an example of how to
decompose your model into code.
 
In the future, please use the repast-interest list and not repast-developer.
repast-developer is for developer communication and issues with the
development of the software itself. repast-interest is for model development
and user support. Thanks.
 
Nick

Hi,

i wanna work on a sahred taxis problem and traffic simulation for a town ;
with multi objectif constraints in wich i must satisfy clients demands in
real time.
I wanna model my problem by using a decentralised approch in wich each taxi
optimise its ways trying to satisfaying 
an economic probem and every client requests. the scenario is :
1 A client call the central.
2 The central sends a broadcast message to the taxis in the geographical
zone from wich the client desires to go .
3 The concened taxis will negociate between them for choose the most
appropriate one to serve the client; these taxis must negociate directly
(and not via the environement as in ant algorithm
in wich each ant follows pheromon deposed by other ants)
 I hope know if it is feasible in repast simphony because in many multi
agent platfrom, the communication between agents is not direct and pass via
the environement.
is it feasible in simphony??
is  there any documentation about this subject??

Thank your for your help
