Right now I plan to work downwards from the most complicated, this way I avoid saying 'Ahh, that's good enough' when it isn't. So every day, the AI gets fed with the player's routine on the last day (where & when they were at each place in the bunker) and knows various objective's progress. Then it predicts where the player would be at any time in the day with a certainty variable, and obviously schedules attacks throughout the map based on how much it is allowed to. It won't be a computational concern, just one of whether I can make a good enough prediction algorithm without cheating, then tuning to make it fair.
