can go wrong. First and foremost, an agent might fail to execute#R##N#one of the planned actions for some reasons. Even more#R##N#annoying, however, is a situation where the agent is incompetent,#R##N#i.e., unable to come up with a plan. This might be#R##N#due to the fact that there are principal reasons that prohibit a#R##N#successful plan or simply because the task’s description is incomplete#R##N#or incorrect. In either case, an explanation for such#R##N#a failure would be very helpful. We will address this problem#R##N#and provide a formalization of coming up with excuses for#R##N#not being able to find a plan. Based on that, we will present#R##N#an algorithm that is able to find excuses and demonstrate that#R##N#such excuses can be found in practical settings in reasonable#R##N#time.
