Worst-case optimization

Definition

Worst-case optimization is a strategy that focuses on minimizing the maximum possible loss or failure in a given design or system. This approach is particularly relevant in scenarios where uncertainties or variations can lead to significant deviations from expected performance, allowing designers to create solutions that are robust against the most extreme conditions.
