1. Adjusted kKelly for bet stakes

The Adjusted Kelly Criterion is a sports betting strategy that helps bettors determine the optimal amount of money to bet on a particular outcome based on the perceived value of the bet.

The Kelly Criterion formula calculates the optimal bet size based on the perceived value of the bet and the bettor’s bankroll. However, in sports betting, there can be additional factors to consider such as the uncertainty of the outcome and the risk of ruin. The Adjusted Kelly Criterion accounts for these factors by modifying the original Kelly formula to include a safety factor or a risk adjustment.
