Now, I said nothing about the dragon in the last exercise.
Let's suppose that it's
deadly than the wumpus, because it can shoot flame from one cave to
another - but it can't shoot further than that.
Can you translate
into Prolog, ``the player (
fred) will be burnt alive if he is
in a cave that is next to the one the dragon is in''.
will_be_burnt_alive( fred ) :-
Test your answer by moving the player and dragon to various caves, and asking
will_be_burnt_alive( fred ).
You may have a problem to do with unidirectionality (I won't say more than that because it may let the game out of the bag). When you think you have tested your new fact adequately, and you are either satisfied, or you have got something wrong and can't see how to continue, please go to the next section. But try this one first.
