 * 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 $$= \frac{FV_1 FV_2}{t^2}\ $$
