AW: Repast-interest digest, Vol 1 #866 - 4 msgs

Taymaz Khatami
Thanks everybody fort he contributions.

I tried to generate a 10000 (ten thousand) Nodes SmallWorld on Friday with
rudimentary agents (which means I cleared all methods, variables and
implemented the agents as default and not as drawables, and had to set the
java heap to 1GB). It took only 20 sec. to generate the Network. I guess my
agents were just too overloaded with methods and variables and the drawings
took a major part of it.

Always keep it as simple as possible.

I think there might be a bug somewhere in your code. I've been working
with RePast generating networks on a computer slower than yours and
generating networks has never taken any significant amount of time. As
Nick Collier said, less than a second should be the amount of time
needed.

I know that visualizing networks takes _a_lot_ of time, once you get
past a few hundred nodes. So if you are displaying the network, that
can at least be a contributing factor.

But, I'd check for anything in the code around where you generate the
network and see if there is something that slows you down there. There
might be some accidental loop or similar. You shouldn't need more CPU
power.

I'm having the same problem. The globe flashes but
there is no change to the display. In my case the data
does look as though its being updated.

One place you may want to look in particular is at the construction code
for your node and edge classes. The create methods use reflection to
build your nodes and edges using the default [ClassName()] constructor,
so I'd check through what happens when you create an edge/node with that
constructor and see if any wierd behavior is going on.
