Several children are playing outside.
After playing they come inside, and their mother says to them, “At least one of you has mud on your head!”
She then asks the following question, over and over:
“Can you tell for sure whether you have mud on your head?”
Each child can see the mud on others, but cannot see his or her own forehead.
The children make no direct communications to one another, they can only chose to step forward to get clean, or not.
Maybe if we start with the right base cases we can figure this out…
(this is what we call a degenerate case)
