It's often laughable. I would think of it like this. Each action can be represented as a polynomial that calculates the value at a time based on time:

v(t) = c1*t^n + c2*t^(n-1 )+...+c3*t+c4

I would think of the value function of the decisions in my life to be the sum of the individual value functions. With every decision I'm presented with multiple functions, and I get to pick one and the coefficients will basically be added into my life's total value function.

Consider foresight to be the ability to predict the end behavior of v for large t. If t=1000 means... (read more)
