= Multiplicative weight update method
{wiki=Multiplicative_weight_update_method}
The Multiplicative Weight Update (MWU) method is a technique used in optimization and game theory, particularly in the context of online learning and decision-making scenarios. It is designed to help agents update their strategies based on the performance of their previous decisions. The key idea is to modify the weights (or probabilities) assigned to different actions based on the outcomes of those actions, with the goal of minimizing regret or maximizing payoff over time.
