Re: Circle

[donalson]

You don't actually need a space object to model this, although it is useful
for display purposes.  If you want to model a "ring" structure, as part of
each bank object have two id's, say neighborLeft and neighborRight.  When you
create the objects you can then add in the adjacencies.  You can model the
center of the "wheel" the same way, but you might want to make it a array of
id's with length equal to the number of banks in your simulation.

If you want to add space to it, just put the id's for your agents into an
object 2D grid.
In pseudo code: (This is NOT executable code!)

id  <Grid2d>  myWorld;
aBank=[Bank create begin];
[myWorld putObject: aBank atX:  5  Y: 7]

Now you can literally just chose your x's and y's to make a pseudo-circle in
the grid, and of course you put the non-bank in the center of the circle.

You can then steal the heatbugs display method to use shades of color to
display relative and/or absolute values of each objects internal variables.

I know this is a bit terse, if you want more help, let me know, I have already
coded up most of this.  Also, the configuration you are looking at is (or at
least was) a way to due distributed processing in computer engineering.  There
may be some research out there on the characteristics of this type of system.
