How do you make peace with an AI empire?

send in ships for them to kill (which usually makes them feel better if they win some fights).

Now see, that one makes them madder as well, as can be seen in the appropriate AI_Anger.txt file (if you wanna cheat and know everything about the race )

Whats great is stalemates. That does make them happy. Turtling yourself in with mines at choke points, littering their space with engine destroyed hulks (that maybe easier for bbq's Version of SE4, the engine destroyer skipped shields in older Versions of SE4). Or just send heavily shielded ships with "Don't get hurt" strategy against weak targets.

The AI will sue for peace, sometimes just long enough to pass a mass of satelites.
