contour planting

For problems whose objective function or constraint functions have sharp curves on their contour maps ( such as the rosenbrock ' s function which has banana shape contours ) , monotonicity may cause a series of very small steps , causing a huge number of iteration to reach their solutions . by using the nonmonotone technique , we get the sequence of successful interative point which should make the objective function mono - tonically decreasing . hence , we use both trust region strategy and line search technique and make each iterate generate an acceptable trial step in interior feasible set as next interative point 我們利用非單調技術得到使目標函數非單調下降的迭代點,因為非單調克服高度非線性化函數的求解問題,從而避免了只使用單調搜索在“峽谷”現象局部最優解被卡的情況,我們用信賴域策略和非單調線搜索技術相結合的方法,使算法產生的迭代步落在可行域內點,同時又在信賴域內滿足接受準則。

The calibration of flow model is acceptable with average rms of 0 . 7m , residual mean of - 0 . 045 m , average absolute mean error of 0 . 1 m and normalized rms value of 2 . 3 % . the contour map of the simulated heads , elaborated acceptable model calibration compared to observed heads map 模型結果中,均方差為0 . 7m ,平均誤差為- 0 . 045m ,平均絕對誤差為0 . 1m ,標準均方差為2 . 3 ,模擬地下水流場與實際觀測地下水流場基本一致,說明所建立的數值模型符合該地區的實際水文地質條件。
