Re: [Swarm-Modelling] Literature on modeling concurrency

[Rick Riolo]

The Huberman and Glance article does show a simple
case of how "scheduling" can affect results, but
I recommend that people also read the article that
it critiques:

   Nowak, Martin and May, R.M -- "Evolutionary games and spatial chaos," 
   Nature, 359, pp826-829. 

and then the "reply" article:

   Nowak, Bonfoeffer and May. "Spatial games and the maintenace of 
   cooperation."PNAS (USA), v91, pp4877-4881. 1994 

Another example of the affects of simple changes in scheduling
are included in this paper:

  Axtell, Axelrod, Epstein, Cohen.  "Aligning Simulation Models: A Case 
     Study and Results."   CMOT 1: 123-141 (1996)

There are quite a few other papers about sync vs async updating
in CA's, too.
