Re: [Swarm-Support] How to terminate a GUISwarm?

[Paul Johnson]

Advice from someone who tried and failed: don't try to do it this way. 
Instead, write the model so you can re-start it from the command line 
with various options and a set random number seed. In the directory 
called memos under the SwarmFaq directory, there are several notes about 
how Java users can process command line arguments.  If you want to run a 
model many times, in various batches with various settings, the command 
line approach is the way to go.

Shutting down the simulation and re-starting another seems like a great 
idea and I even had a working prototype "RepeatingHeatbugs" at one time, 
but it never was stable and now does not run at all.  The problem is 
that you need to completely clean out everything in memory and get a 
fresh run at it to get truly manageable replication, and the 
simpleExperBug approach just doesnt work very well.  I talked to several 
of the core development team who advised me not to pursue that 
approach.  That's why the newer tutorial has the explanation about 
running batches with command line options.
