An island is home to n (>=1) blue-eyed, m (>=1) brown-eyed and 1 green-eyed perfect logicians. Nobody knows his own but knows everyone else's eye colour. There is no communication between islanders except that on the first day the green-eyed logician (who is known never to lie) states: "I can see a blue-eyed person." Every evening a ship passes the Island and anyone who logically deduces their own eye colour can leave on that ship. Who leaves and on which days do they leave?
