Las Vegas Algorithm

A Las Vegas Algorithm is a type of randomized algorithm that always produces the correct result but may take varying amounts of time to do so. It uses randomness to guide its process, making decisions unpredictably, which can lead to faster solutions in some cases. However, unlike other algorithms, it never outputs an incorrect answer; if it doesn't find the solution right away, it keeps trying until it does. This approach is useful when correctness is critical, and sometimes, the expected time to find a solution is acceptable despite variability.
