Abstract
In this paper, an extensive numerical examination of the Two-Point Adaptive Nonlinearity Approximation, TANA-3, is provided. This function approximation method is tested against a set of 18 real-life design optimization problems. A complete set of 97 cost and constraint functions and 7049 function approximations were performed and compared with exact values. Majority of approximations performed by the Two-Point Adaptive Nonlinearity Approximation algorithm possess high accuracy and low computational cost. Therefore, this method is highly appropriate for application in design optimization. However, some 15% of the performed approximations exhibit significant inaccuracy.
