+A **lower bound** marks the smallest possible value that a function, set, or quantity can take. It defines a floor, ensuring no element or outcome falls below this point, often found in contrast to an [Upper Bound](/wiki/upper_bound). Identifying a precise [Minimum](/wiki/minimum) lower bound is fundamental in fields like optimization and analysis.
