Abstract: Abstract In agriculture and water resource management, evapotranspiration prediction plays an important role. In this article, the optimized SVM models are used for predicting evapotranspiration. In this study, the SVM parameters are adjusted using particle swarm optimization (PSO), antlion optimization (ANO), and crow optimization algorithm (COA). For choosing the best input combination, a hybrid gamma test is used. Automatically, the hybrid gamma test can determine the best input combination. The optimized SVM models outperformed the standalone SVM models. The mean absolute error (MAE) of the SVM-ANO, SM-COA, SVM-PSO, and SVM models was 0.678, 0.789, 0.812, and 0.824 at the Iranshahr station.
