# Maximally Mutually Beneficial

Assuming we could calculate Utility values for given circumstances (we can’t), I define:

*D*as the set of future decisions.- F
_{n}(*d*) as the utility the nth individual receives from the future decision*d*in*D*. - The maximally mutually beneficial function as the product of
*F*_{1}(*d*) to*F*_{n}(*d*) for any given d in D. - The maximally mutually beneficial decision as
*B*in*D*such that the*MMB*function of*B*has value greater than or equal to the*MMB*function of any*d*in*D*.

An important properties of *B*: causing anyone’s utility to decrease to 0 or lower results in a very poor score.
