- According to 1), I can divide each kind of goods in the pile
- infinitely too. So, let one player divide the whole pile into N
- portion each containing same amount of each kind of goods. No one is
- allowed to modify the portions any more. Everyone picks one portion.
- Everyone should be happy. If not, *tough*. Selecting the biggest
- player to divide the pile would help too.
