[Q]

The two files that determine the response of the AI to treaty proposals are the anger and politics files. If you changes the values there you will get the AI to accept a treaty after beeing at war with you.
Give a higher value to "Accept Treaty Base Anger Level" and to reduce the value for "Turns Since Last War Before Friendly Treaty" will be the most important changes, but you may try to change other lines as well. Good luck!
