“…As a result, a large number of metamodels have been proposed, of which several types have gained wide acceptance in various applications. They are polynomial response surface (PRS) [12][13][14], support vector regression (SVR) [15][16][17], radial basis functions (RBF) [18,19], extended radial basis functions (E-RBF) [20], moving least squares (MLS) [21], artificial neural networks (ANN) [22,23], multivariate adaptive regressive splines (MARS) [24] and Kriging (KRG) [25,26]. These different metamodels give us more options for different tasks.…”
