 Robertson–Webb envy-free cake-cutting algorithm

The Robertson-Webb envy-free cake-cutting algorithm is a mathematically rigorous method for fairly dividing a resource, often referred to as a "cake," among multiple parties (or "players") in such a way that no player envies another. This algorithm is particularly relevant in fair division problems where the goal is to ensure that all parties receive shares that they perceive as equal in value or utility, thereby eliminating any feelings of envy.
