On odds, the computer cannot do it. Here is what I know about the mistakes it makes:

IT thinksthat chariots are mighty, so Egypt is the most powerful faction

It thinks that light cavalry are useless

It forgets the massive advantage a defender has in a cityfight, and the small one in a field battle.

It doesn't takeinto account mass routs

I think it just does sums like:

Total Defense*hit points - Total Melee attack +charge bonus for attacker.

Then repeats, and does the same minus the charge bonus until one side dies. So, it just thinks that everyone is going to bloodily clash.
