Randomized Algorithms

Definition

Randomized algorithms are computational procedures that incorporate an element of chance in their logic or input processing. These algorithms make random choices during their execution, often to achieve better average-case performance or to simplify design for complex problems. In cryptography and distributed systems, they can be used for tasks like leader selection, fair resource allocation, or generating unpredictable outcomes. Their effectiveness relies on the quality of the random numbers employed.
