Definition: Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.
Input: THEM: i would like the ball and 3 books  YOU: i understand your attraction to that deal, but i require more. i need two of the books if you are taking the only ball.  THEM: you can have the 1 hat and 1 book if i get 2 books and 1 ball  YOU: no, i need to be compensated fairly for the ball. you can have that ball for two books.  THEM: i'll take 1 book, 1 hat, and 1 ball then.  YOU: yo u are offering even less to a bald man now. i need the hat along with two books if you want the ball.  THEM: no deal, that wouldn't be fair to me either.  YOU: it would be quite fair. we would each get something we need and as a fast reader i get two books.  THEM: considering each item varies in points for both of us, no it's not. i'd like the ball and 2 books, otherwise no deal.  YOU: as you seem passionate about both books, i can let you have two along with the bowl in exchange for future considerations.
