Thanks, Steven, From my initial Googling the closest I could find was Drools<http://jboss.org/drools/>. It's intended to provide a forward chaining rule programming language for distributed systems (J2EE). It's open source from JBoss. Although it has nothing to do with Agent-based modeling, it seems quite nice and quite general. It runs on top of and is completely integrated with Java. Agent can simply be an object type. Its Template<http://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-expert/html_single/index.html#d0e5774>capability allows it to generate rules that are stored as Java objects, which seems to make it capable of manipulating rules dynamically. I'll have to look into that further. One can make it a simulation engine by keeping a tick counter in the workspace.
It would be nice, though, if there were a system already developed for this sort of thing. Now that I know what I want, it seems like such a natural and powerful kind of modeling capability that it's amazing that it hasn't been done! -- Russ On Sat, Aug 22, 2009 at 8:58 PM, Stephen Guerin <[email protected]>wrote: > Russ, > > I haven't seen a system like your describing.
