This problem is similar to the missionaries and cannibals problem puzzle. One additional twist to the missionaries and cannibal problem in this problem is the fact that rather than being all the same, men and women have roles and although it appears to complicate the solution, it really does not.

**Problem:**

Three jealous husbands and their wives need to cross a river. They find a small boat that can contain no more than two persons. Find the simplest schedule of crossings that will permit all six people to cross the river so that none of the women shall be left in company with any of the men, unless her husband is present. It is assumed that all passengers on the boat unboard before the next trip and at least one person has to be in the boat for each crossing.
