    Abstract: 本文發展與建構兩點保守近似函數,替代限制條件中無顯函數的優化問題。以修正凸線性近似為基
    經QcTCA 函數的數值性能測試分析,並與修正凸線性近似法做比較,討論其誤差性及準確性。由文
    果, 驗證本文所提出的準三次兩點保守近似法於優化設計的有效性與應用性。
    Two point approximation of a function are currently recognized as the formal approach that can be applied to
    large-scale structural optimization problems or to implicit functions, such as the function computed by finite
    element analysis. To achieve the stable and efficient convergence, the conservative function approach has
    been proved to be a practical application in optimization process. This paper develops a Quasi-cubic
    two-point conservative approximation (QcTCA) integrated in structural optimization, based on modified
    convex approximation (MCA), that include quasi-cubic term in the Tayler series approximation. The
    results show that not only a limited and stable iteration times can be maintained but also a relative precise
    results can be obtained.
