% 0.17/0.63  % Problem  : Missionaries and Cannibals
% 0.17/0.63  % Version  : Especial.
% 0.17/0.63  %            Theorem formulation : Declarative, without subsumers.
% 0.17/0.63  % English  : There are 3 missionaries, 3 cannibals, and a boat on the west
% 0.17/0.63  %            bank of a river. All wish to cross, but the boat holds
% 0.17/0.63  %            at most 2 people. If the cannibals ever outnumber the
% 0.17/0.63  %            missionaries on either bank of the river the outnumbered
% 0.17/0.63  %            missionaries will be eaten. Can they all safely cross the
% 0.17/0.63  %            river?  If so, how? (The boat cannot cross empty.)
