It is all based on 'agent theory' up to the actual point of battle itself. They are not trying to recreate battles, just the figure out what physically led up to them.

Status: offline 		Now that is interesting. Out of scope as they are looking at the middle ages, but I wonder if anyone can work out the likely realistic numbers for the Persian army that invaded Greece, leading to the Battle of Thermopylae. One million seems a tad excessive after all.....

Will be really interested to hear their conclusions.

From what I've read, most historians believe the Persians numbered closer to 100,000-250,000. Of course, even that's still a huge frickin' army for the time period, and would require an impressive feat of logistics regardless!

Indeed - especially when you have just 300 Spartans taking them on

Its basically a fancy way to say "models based on the emergent dynamics among autonomous or semi-autonomous decision-making entities (people, organizations, organisms, etc.).

Agen Based Model

You define the paramenters you want to manipulate, in put the estimated values for various agents, etc. then let it run repeatedly for appropriate stretches of time, and then you compare the frequency with which you get various final outcome states.

Computer games with "AI" are a sort of agent-based modelling, though the intent there is to challenge the human player not to model realworld or hypothetical ecological dynamics.

Actually, it was more like 5000-7000 allied Greeks (including the 300 Spartans) -- the poor Thespians never get the recognition they deserve! That being said, yeah, they were still pretty thoroughly screwed either way.

Tnx, but isn't that also how forcasters now "predict" the weather?
