In mathematics, the expression "n ≥ n₀" indicates that a variable n is greater than or equal to a specific value n₀ . This notation is often used in the context of limits, sequences, or algorithms to define a threshold beyond which certain properties or behaviors hold true. For example, in algorithm analysis, n₀ might represent the minimum input size for which an algorithm's performance can be reliably assessed. Understanding this concept helps in evaluating how algorithms behave as the input size increases, particularly in relation to their efficiency and complexity.
