I don't know if this is what you were refering to or not - here it is.  http://www.suncoastrewards.com/ref44.html
You can file share dvd's, video games & music.  I've already downloaded 6 console games and music CD's..
I can't wait untill you get a load of this selection of games & music & movies - it's nuts.
Theres this awsome section of the site that shows you how to burn the games & music and movies to CD.
I noticed in the movie section over lunch, they have titles for download that are still in theaters - it's fantastic.
Talk to you tommorow.

[Repast-developer] Scaling bug in uchicago.src.sim.gui.Network2DDisplay.java

[David D. <dde...@cs...>]

Greetings, 

I am a new user of RePast 2.2.  I am building a simulation that uses 
RePast's network visualization capabilities.  

I believe I've found a bug in the way Network2DDisplay manages the scaled
width/height of its nodes and its SimGraphics instance.

The issue is that 
  (1) the nodePoint hash table contains scaled widths and 
  heights for the nodes.  (See lines preceding every
  nodePoint.put(...) call in Network2DDisplay.java.)
Yet 
  (2) when Network2DDisplay sets up the SimGraphics instance (g) 
  before letting the nodes draw themselves, it does a 
    g.setDrawingParameters(nodePoint width entry, 
                           nodePoint height entry, 
                           0)
  rather than a 
    g.setDrawingParametersNoScale(nodePoint width entry, 
                                  nodePoint height entry, 
                                  0)
  which I believe it should do.

The result is that the SimGraphics instance then rescales both the 
width and height parameters *again*, so that graphics drawn with 
SimGraphics.drawX method calls grow/shrink faster as they should. 

One quick way to see that there is a problem is run the demo/jiggle.jar 
and note that the links do not connect the center of masses of the 
nodes as the window is scaled.  The links connect where the center 
of masses *should* be. 

Without really understanding all the RePast code, I believe the 
fix is to replace very 
  g.setDrawingParameters 
call in Network2DDisplay.java with a corresponding 
  g.setDrawingParametersNoScale
call.

Works for me.  And fixes the jiggle demo too. 

Cheers,
David DeVault

[Repast-developer] Repast 2.2 Jar contents

[Mark R. D. <mdi...@la...>]

After a little break, I'm getting back into some RePast work. I notice 
the following concerning the RePast jar for 2.2

Our experimental topology packages are in the release, however, there 
are missing classes which case compilation errors to occur. Somehow the 
following was left out (or I suspect the real intention was to exclude 
topology entirely and only the classes in the root topology directory 
were the ones actually excluded).

Missing classes:

u.s.s.topology.Context
u.s.s.topology.ContextFactory
u.s.s.topology.DefaultContext
u.s.s.topology.DefaultModifyableContext
u.s.s.topology.DefaultModifyableTopology
u.s.s.topology.ModifyableTopology
u.s.s.topology.RelationTopology
u.s.s.topology.DisplayableContext

I may end up working on some Display classes for all topoloy stuff in the near future.


Note: We should also discuss what we are going to do about the last attempt to modularize the project. I believe currently there is work in both the original repast directory and the mavenized one which is out-of-sync. 

I'm tempted to suggest that we learn alot from last winters attempt and we should evaluate what went right/wrong with it and explore attempting it again now that tools such as maven have matured a bit.

[Repast-developer] Distributed RePast using HLA

[Robert M. <R.M...@cs...>]

Hi all,

I've been working with RePast since last summer, trying to integrate it 
with the distributed-simulation protocol 'HLA', developed by the DOD and 
now an IEEE standard (1516).

There is information about HLA, the mechanisms and the protocol here:

https://www.dmso.mil/public/transition/hla

The middleware I've been developing to make RePast talk to itself through 
the HLA is finished, we've created some benchmarking models, run some 
performance tests and written a paper.

This paper will be presented by me next week at the European Simulation 
Interoperability Workshop (EURO-SIW), information about the conference can 
be found here:

http://www.sisostds.org/siw/04Euro/

If, by any chance, somebody on this list will be around, drop me or my
supervisor a line (R.M...@cs... or 
G.K...@cs...) and we can meet up for a chat if you're
interested.

Other than that, just thought I'd put the information out there as I think 
it is pertinent in some way at least to RePast development.

Regards, Rob.

[Repast-developer] one bug in the class of uchicago.src.sim.gis.LineStringAdapter?

[yy <yon...@so...>]

dear all,

I want to develop some GIS functions in the Repast frame. When I try to =
display multilinestring in GisDisplay, I find one bug in the class of =
uchicago.src.sim.gis.LineStringAdapter.(It seems there is no =
MultiLineStringAdapter in the gis package)

the bug is in the function of setGeometry(Geometry geo).
the code is as following:
*************************************************************************=
*******************************************************************
public void setGeometry(Geometry geo){
       if(!geo.getGeometryType().toLowerCase().equals("linestring") &&
                =
!(geo.getGeometryType().toLowerCase().equals("multilinestring"))){
            throw new IllegalArgumentException("This is not a =
linestring, it is a " + geo.getGeometryType());
        }
        if(geo.getGeometryType().toLowerCase().startsWith("multi")){
            multi =3D true;
        }
        LineString line =3D (LineString) geo;
        super.setFrom(new PointAdapter(line.getStartPoint()));
        super.setTo(new PointAdapter(line.getEndPoint()));
        Coordinate[] coords =3D line.getCoordinates();
        points =3D new LinePoint[coords.length];
        points[0] =3D new LinePoint(coords[0]);
        points[0].setToPoint(points[1]);
        if (points.length < 3) {
            points[1] =3D new LinePoint(coords[1]);
            points[1].setFromPoint(points[0]);
            strength +=3D GisUtilities.getDistance(coords[0], =
coords[1]);
        } else {
            for (int i =3D 1; i < coords.length - 1; i++) {
                points[i] =3D new LinePoint(coords[i]);
                strength +=3D GisUtilities.getDistance(coords[i], =
coords[i - 1]);
                points[i].setFromPoint(points[i - 1]);
                points[i].setToPoint(points[i + 1]);
            }
            points[points.length - 1] =3D new =
LinePoint(coords[points.length - 1]);
            points[points.length - 1].setFromPoint(points[points.length =
- 2]);
            strength +=3D GisUtilities.getDistance(coords[points.length =
- 1], coords[points.length - 2]);
        }
}
*************************************************************************=
*************************************************************************=
******
at first, this code judge if this geometry is a linestring or =
multilingstring or even neither, if this is a multiline, the multi sign =
will be set to be true, all these are right.
but then it try to force the geo to be a lineString without any =
judgement. When I use this function, my geo is a multiLineString, so =
there will be Exception thrown.
This error are so obvious that I donot sure if this can be called a bug. =


thank you very much!

Ibiblio really has nothing to do with it. Its all Apache/Maven 
developers who establish these mandates to cover their ^$$. The process 
to get most jars onto the repository is rather simple.

Yes, its important that the jars are distributed from their "origin". If 
repast is modifying something and repackagin it, repast should be able 
to distribute it, If its just a tool, we go to the canonical developers 
and approach them to ok its distribution. Yes, the real stinker is Sun, 
they are very restrictive about redistribution ( it really hurts the 
community overall in a big way ). Those jars will have to stay outside 
of Ibiblio and be distributed with the application. In such situations, 
RePast Developers can either start with a RePast distribution including 
it or go get it from Sun themselves.

I suspect theres going to be some growing pains here because there have 
been changes to the original tree that are not in the Mavenized 
"branch". I suspect we would need to go through and "catch up" with 
those modifications.

repository there for GeoTools.

They seemed quite strict about ensuring that all jars are properly
licensed for redistribution.  I was in the middle of verifying this
when I got distracted by my dissertation.  (The issue was complicated
by the fact that some of the jars distributed with RePast originate
with Sun and either don't contain licenses or contain licenses without
explicit redistribution clauses.)

I'd be happy to pick this up again if there's interest.  Be warned,
though, that getting into compliance might require moving to later
versions of jars or refactoring to eliminate dependencies.

(This would also reopen the question of whether it makes sense to move
to a Mavenized build process.  As you remember, it was still pretty
bloody when we experimented with it in the fall, but possibily the
benefits would outweigh the costs.)

[Repast-developer] Maven, Repast Development and Ibibilio

[Mark R. D. <mdi...@la...>]

Hi All,

I have some news in terms of RePast development and resources. I'm 
currently involved with both the Ibiblio and Apache Maven Jar 
Repositories. So if we're looking for a home for repast jars. We can 
work out the details easily to get them published at:

It seems to be broken at least since May 4.

Below is the response I got back then.

Hi there,

I am writing a simulation in RePast and would like to get involved in the 
development of RePast itself, particularly the way how experiments are set up 
and data representation - manipulation.

Cheers,

RE: [Repast-developer] repast alive ?

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

All,

RePast development is very much alive. We did a release fairly recently and
there are some exciting developments planned for the future, particularly in
the GIS area.

I'm assuming that the re...@sr... address is just broken now for
some reason. We'll look into it.

Re: [Repast-developer] repast alive ?

[Robert M. <R.M...@cs...>]

Hi Volker, Hi everyone,

I've never been involved directly with repast development at the cvs level 
but I've spent the last 12 months using it extensively in my PhD research. 

I've been writing some extensions to make it run as an hla-compliant 
distributed simulator. It's still very much a research toy at the moment 
but we have results and the paper is being presented by me this summer at 
the European Simulation Interoperability conference in Edinburgh. We are 
also submitting an extended version to a journal some time soon. If anyone 
has a copy of an HLA runtime infrastructure and would like to play with 
the (non bug-free) distribution libraries I'd be happy to package them up 
and send them out - I guess they would just inherit the RePast GPL.

I certainly hope that the direct developmental community (as in those who
_do_ touch the cvs as opposed to people like me who just tinker with the
api's on their own) has not disintegrated, particularly considering the
popularity of RePast - there are 4 agent researchers in my department
alone who use it on a regular basis.

[Repast-developer] repast alive ?

[Volker N. <vo...@cs...>]

Hi there,

I wonder if the repast development is still alive.

I send a number of mails to re...@sr... to make contact.

All of them were returned: connection refused. 

Who is coordinating the development at the monent?

Greetings,

[Repast-developer] OpenHistogram question

[Michal K. <mic...@ce...>]

Hello guys,

I'm using OpenHistogram in my simulation and I have created it this way:

----------------------------------------------------------------
//part of model class
histogram = new OpenHistogram("title", 7, 0, this);

histogram.setLocation(450, 450);
histogram.setAxisTitles("colonies", "average time");
histogram.setXRange(-1, 8);
histogram.setYRange(0, 1000);
histogram.setXTick(0, "t 1");
histogram.setXTick(1, "t 2");
histogram.setXTick(2, "t 3");
histogram.setXTick(3, "t 4");
histogram.setXTick(4, "t 5");
histogram.setXTick(5, "t 6");
histogram.setXTick(6, "t 7");
histogram.createHistogramItem("colony times", histogramList,
"getColonyNr", -1 ,2);

histogram.display();
----------------------------------------------------------------

then I normally call:

----------------------------------------------------------------
histogram.step();
----------------------------------------------------------------
scheduled of each tick.

My problem is this: at the beginning of simulation, when I click
'Initialize' button in RePast toolbar, it gives empty nice histogram
(see first attached picture), with proper labels 't 1', 't 2', 't 3',
't 4', 't 5', 't 6', 't 7' on x-axis. But when I start simulation with
either 'Step' or 'Start' button, the histogram gets filled with proper
values, but my 't 1', 't 2', 't 3', 't 4', 't 5', 't 6', 't 7' labels on
x-axis all disappear (see second attached picture) and are replaced with
strange numbers instead. I don't want this happen - I want to keep my
labels instead of these strange numbers (btw., what do they mean mean?).

How can I do it?


Thx, in advance

Michal

RE: [Repast-developer] Genetic Algorithm

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

Jeff,

Well, both approaches would be useful, I think. I had to pick I guess I'd go
with the agent level one. If you post this query on repast-interest, you may
get more responses as the number of subscribers is much larger.

[Repast-developer] Genetic Algorithm

[Jeffrey F. <jja...@ch...>]

In the process of coming up with a GA implementation for Repast, I have 
come up one the question, what level make the most sense. Essentially, 
I have devised three different levels that could all make sense in 
their own way. At the lowest level, you could setup a GA that runs for 
each agent evolving an ideal set of behavior values. The next level up 
would evolve the population of agents in order to achieve a "perfect" 
agent. The option would be to have a GA consist of a population of 
models, which would yield a best model.

What level you think would make the most sense for implementation into 
Repast?

[Repast-developer] Release 2.2

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

All,

I'm happy to announce the release of repast v. 2.2. You can get it at:

http://sourceforge.net/project/showfiles.php?group_id=1703

Note that this version requires java 1.4 or greater. It was built and tested
with 1.4.2_04.

Currently, there are only .zip and .tgz archives available. I'll make
executable installers for Windows, Linux and the Mac and post them early
next week.

Release Notes follow:

RePast 2.2

This is primarily a release to distribute the many bug fixes that have
accumulated since the last release.

Thanks to Thomas Howe, Mike North, Jason Woodard, David O'Sullivan,
Laszlo Gulyas, James Macgill, Mark Diggory, Robert Najlis, Luc Girardin
(and anyone else I may have forgotten) for their contributions and also to
Argonne National Laboratory for supporting this release.


** New Features

*** Single run batch mode. Can perform a single batch run without a
parameter
file using: uchicago.src.sim.engine.SimInit -b MyBatchModelName

*** Multiple run batch mode. Can perform mulitple batch runs without a
parameter
file using: uchicago.src.sim.engine.SimInit -b MyBatchModelName num_runs

*** New batch parameter file format (the old one still works as well). Email
Nick (nic...@al...) for details if interested.

*** Refactored parameter mechanism that makes it much easier to control
batch runs with custom parameter iterators.

*** Additional refactoring of the controller heirarchy.

*** Console output redirected to repast console window. This can be
turned on/off with AbstractGUIController.CONSOLE_ERR = true/false and
AbstractGUIController.CONSOLE_OUT = true/false.

*** New CallbackSchedule class that allows for the scheduling of methods
that take arguments

*** Experimental support for "Group" operations; that is, agents can be
added to a DefaultGroup and this DefaultGroup can be used to execute
methods, take statistics etc. over all the agents in that group.

*** Removed dependencies on Acme, jgl, and xerces jars.

*** Node / edge drawing order is specifiable

*** Improved support for running distributed simulations; that is,
for running many simulations on many machines under the control of
a single computer.

** Bug Fixes

*** Fixed the xml parsing problem with Frame and Chart
persistent positioning.

*** Controllers respect the ExitOnExit flag.

*** Fixed snapshot problem on charts and graphs (i.e. "too many colors").

*** Fixed problems with finding the demo and models directory when
using the "load model" button in the repast toolbar.

*** Fixed problem where gui event queue is assumed to exist on
all machines. This should fix problems with running batch models
in a unix enviroment without X11.

*** Misc. small bug fixes.

[Repast-developer] RePast is the "Most Suitable Simulation Framework" for Social Modeling

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

Here is some interesting news.  Robert Tobias and Carole Hofmann's =
recent "Evaluation of free Java-libraries for social-scientific agent =
based simulation" in the Journal of Artificial Societies and Social =
Simulation (JASSS)(Vol. 7, No. 1) states that:

Despite the problems with the evaluation mentioned above, we can =
conclude with great certainty that according to the available =
information, RePast is at the moment the most suitable simulation =
framework for the applied modeling of social interventions based on =
theories and data. It is certainly worth realizing a project in this =
framework and then, on the basis of experience gained, and taking into =
account the new state of development in the rapidly evolving area of =
social simulation, conducting the evaluation again.
