The smoothing constant alpha ($\alpha$) is a parameter that determines the weights assigned to observations in exponential smoothing. It controls how much priority or weight is given to the most recent actual data versus the historical forecast, with newer data receiving higher priority.

Conditions: $\alpha$ is a smoothing parameter or constant.; It is used in time series forecasting to assign exponentially decreasing weights to past observations.; The domain of $\alpha$ is typically $0 \le \alpha \le 1$.
