SUMMARY

The discussion revolves around a logic puzzle involving a mother, father, two sons, two daughters, a criminal, and a cop needing to cross a river using a boat that accommodates two individuals. Key constraints include the mother not being allowed with her sons without the father, the father not being allowed with his daughters without the mother, and the criminal only being allowed with the cop. The solution involves a series of crossings that ensure all conditions are met, demonstrating a structured approach to solving complex logic problems.

A little harder then the lion/goat/cabbage but easier (IMO) then the King/Queen/Peasant+wifes.

A mother, a father, two sons, two daughters, a criminal and a cop need to cross a river. They have a boat for two, as usual in these situations.

1. The mother cannot be in the presense of any sons unless the father is present.
2. The father cannot be in the presence of any daughters unless the mother is present.
3. The criminal cannot be in the presence of anyone unless the cop is present.
4. Only the father, the mother and the cop can operate the boat.
5. "being in the presence of" includes both sides and the boat.
6. Any oddball logic mistakes I made in writing this are mistakes, not an indication that this is some kind of word puzzle rather then a logic puzzle.

Cop takes the boat back.
Cop and one daughter cross.
Cop and prisoner cross back.
Mother and daughter cross
Mother takes the boat back.
Mother and father cross
Father takes the boat back
Cop and prisoner cross

Correct. Not that you need me to tell you :-).
