Discounted Perceived Value of all Future Interactions $=\sum _{t=0}^{N}{\frac {FI_{t}}{(1+i)^{t}}},$

$DPV=\int _{0}^{T}FI(t)\,e^{-\lambda t}dt\,,$

Perceived Value of current Friendship Interaction $=FI_{t=0}$

Discounted Perceived Value of all Past Interactions $=\sum _{t=0}^{N}{\frac {PI_{t}}{(1+i)^{t}}}$

$FV=\sum _{t=0}^{N}{\frac {FI_{t}}{(1+i)^{t}}}+FI_{t=0}+\sum _{t=0}^{N}{\frac {PI_{t}}{(1+i)^{t}}}$

Relationship Value $={\frac {FV_{1}FV_{2}}{t^{2}}}\$
