Monte Carlo Localization (MCL) is a probabilistic algorithm used in robotics to determine a robot's position and orientation by using a set of weighted hypotheses, represented as particles, to approximate the robot's belief state. It efficiently handles uncertainty and noise in sensor data, making it suitable for dynamic and complex environments where traditional localization methods may fail.

Monte Carlo Localization

A probabilistic algorithm is a computational procedure that makes random choices as part of its logic, often leading to different outcomes on different runs for the same input. These algorithms are particularly useful for problems where deterministic solutions are inefficient or unknown, offering faster average performance or simpler implementation at the cost of some uncertainty in the result.

Dynamic environments refer to settings or systems characterized by constant change and unpredictability, requiring adaptive strategies and flexible responses. They are prevalent in fields like technology, business, and ecology, where rapid shifts demand continuous monitoring and agile decision-making.
