Ok,
The main factors involved in whether the AI will accept a ceasefire are war success (not an issue at the start) and power.
There are also some finicky bits around war plans and financial trouble, which also shouldn't affect us at the start.
We can effectively triple our power by threatening one of their cities with a warrior (so long as our cities aren't threatened).
The basic threshhold appears to be that we must have 89% of their power (more for a DoP instead of a CF)
