Following the estimation of parameters, the results of wave prediction models are reported in Table 4. From this table, it can be inferred that in the studied case, the combined FIS and GA models are even more accurate than the ANFIS models where their structures have been optimized by the GA. All of the models have reasonable bias, indicating the accuracy of models for prediction of the phenomenon.
