Given that Agent 1 is more interested in apples and Agent 2 cares more about oranges, the maximum total utility solution would be the case where each agent offers to get all the fruits it cares about and to give its interlocutor all the fruits it does not care about, and the other agent accepts this offer.
when converging to the maximum total utility solution, in the case of 4 fruits (4 ap-ples and 4 oranges), the average reward of the two agents should be 1200 minus 10 for making or accepting an offer.
