           │ > You may recall the puzzle of a ferryman, goat, cabbage, and wolf all on one side of a river. The ferryman can cross the river with at most one passenger in his boat. There is a behavioural     │
           │ conflict between: 1. the goat and the cabbage; and 2. the goat and the wolf; if they are on the same river bank but the ferryman crosses the river or stays on the other bank. We wish to know how │
           │ the ferryman can transport all goods to the other side, without any conflicts occurring. Build a model in which the states represent which goods are at which side of the river. Your model will   │
