It maintains a set of weights for different strategies or experts, updating them multiplicatively based on their past performance. Strategies that perform well have their weights increased, while poor performers see their weights decreased. This method is widely used in game theory, optimization, and machine learning for constructing efficient prediction algorithms with provable convergence guarantees.</p>
