Assuming we could calculate Utility values for given circumstances (we can’t), I define:
- D as the set of future decisions.
- Fn(d) as the utility the nth individual receives from the future decision d in D.
- The maximally mutually beneficial function as the product of F1(d) to Fn(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.
