Emulated the website from The Social Network to compare between two individuals, but with a twist — using actual farm animals instead of human profiles.

Chess Player Ranking Algorithm (Elo Rating)

Given - $Base Rating: 1000$, $K: 32$

Probability of winning for Player A (left), $P_A$

$$P_A = \frac{1}{1 + 10^{(R_B - R_A)/400}}$$

Probability of winning for Player B (right), $P_B$

$$P_B = \frac{1}{1 + 10^{(R_A - R_B)/400}}$$

When Player A wins (left chosen):

$$\text{leftRating} = \text{leftRating} + K \cdot (1 - P_A)$$

$$\text{rightRating} = \text{rightRating} + K \cdot (0 - P_B)$$

When Player B wins (right chosen):

$$\text{leftRating} = \text{leftRating} + K \cdot (0 - P_A)$$

$$\text{rightRating} = \text{rightRating} + K \cdot (1 - P_B)$$
