Therefore, at the moment changing men to missionaries and women of cannibals, any solution to the problem jealous husbands will also become a solution to the missionary and cannibal problem. The program generated this solution from right to left, but (because of the symmetry in this puzzle) its reverse is also a solution. A.I. Darryl. right side X OO. Skills: Algorithm, C Programming, C# Programming, C++ Programming, Software Architecture The only way across is a small boat. All other information can be deduced from these thres items. The main control block is what happens upon the execution of the find command when the Prolog is queried. In PROLOG, the state can be representted by a 3-arity term, state (Missionaries,Cannibals, State). 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).
