Therefore, upon changing men to missionaries and women to cannibals, any solution to the jealous husbands problem will also become a solution to the missionaries and cannibals problem. Under this constraint, there cannot be both women and men present on a bank with women outnumbering men, since if there were, these women would be without their husbands. In the jealous husbands problem, the missionaries and cannibals become three married couples, with the constraint that no woman can be in the presence of another man unless her husband is also present. And, in some variations, one of the cannibals has only one arm and cannot row. The boat cannot cross the river by itself with no people on board. In the missionaries and cannibals problem, three missionaries and three cannibals must cross a river using a boat which can carry at most two people, under the constraint that, for both banks, if there are missionaries present on the bank, they cannot be outnumbered by cannibals (if they were, the cannibals would eat the missionaries). (1) The sphere x2+y2+z 1 is 1 in spherical coordinates.So, the solid can be described in spherical coordinates as 0 1, 0 4, 0 2. The missionaries and cannibals problem, and the closely related jealous husbands problem, are classic river-crossing logic puzzles.The missionaries and cannibals problem is a well-known toy problem in artificial intelligence, where it was used by Saul Amarel as an example of problem representation. that zin Cartesian coordinates is the same as cosin spherical coordinates, so the function we’re integrating is cos.The cone z p x 2+ y2 is the same as 4 in spherical coordinates.
