Abstract
We compared three different approaches for forecasting a time series of the solar activity index: iterations of a single-step model, an independent single-step forecast for each subsequent month, and a single multi-step forecast for the entire period. In each approach we use a neural network model as the forecasting model with the aid of a theoretical series of solutions obtained from the physical model.
