Two chess players has a current elo rating as 5 and 3. Find the updated rating of the players?
Given :
K-factor = 32, Player 1 current rating = 5, Player 2 current rating = 3
Player 1 Transformed Rating = 10(5/400) = 1.0292
Player 2 Transformed Rating = 10(3/400) = 1.0174
Player 1 Expected Score = 1.0292 / (1.0292+1.0174) = 0.502878199574811
Player 2 Expected Score = 1.0174 / (1.0174+1.0292) = 0.49712180042518894
If Player 1 wins, Player 1 Actual Score is 1 and Player 2 Actual Score is 0
Player 1 Updated Rating = 5+32×(1-0.502878199574811) = 21
Player 2 Updated Rating = 3+32×(0-0.49712180042518894) = -13
