The rules are fairly easy. A mother, a father, two girls, two boys, a policeman and a convict are to cross the river with a boat. The conditions are:

• The convict cannot be alone with any member of the family without the policeman.
• The father cannot be with the daugther(s) if the mother is not there.
• The mother cannot be with the boy(s) if the father is not there.
• Only the father, the mother and the policeman know how to sail the boat (so one of them should be on the boat on each crossing)
• The boat holds at most 2 people
