  1. Such methods are generally decreasing method, such as, feasible direction methods, constrained variable metric methods, etc. another class is sub - problems method, which approximates the optimal solution by solving a series of simple sub - problems, such as penalty function methods, trust region methods, and successive quadratic programming sub - problems, etc. the same property of two classes of methods is that they determine whether the next iterative point is " good " or " bad " by comparing the objective function value or merit function value at the current point and next iterative point

    另一類叫做子問題演算法，這種演算法是通過一系列簡單子問題的解來逼近原問題的最優解，如罰函數法、信賴域演算法、逐步二次規劃演算法等。這兩類演算法的一個共同特點是，通過比較當前點和下一個迭代點的目標函數值或評價函數值來確定迭代點的「優」或「劣」 ，若迭代點比當前點「優」則該迭代點可以被接受，否則須繼續搜索或調整子問題。
  2. Our method is based on non - linear convolution model and uses artificial nervous net algorithm and simulated annealing algorithm, introducing the acoustic impedance as condition of constrained solution to avoid the hypothesis of wavelet or reflection coefficient in common seismic inversion, and adopting the control of fine seismic interpretation model in extrapolation

    反演方法以非線性褶積模型為基礎，引入井旁聲阻抗作為解的適定性的約束條件，避開一般地震反演對地震子波及反射系數的假設。反演外推採用精細地震解釋模型控制。演算法上，引用人工神經網路和模擬退火演算法。
  3. To obtain a stable solution, in our method, successive approximation process is constrained by prior histogram and laplacian regularization

    為了獲得穩定而滿意的解，我們採用直方圖約束下的正則化方法對連續近似迭代進行約束。
  4. Taking all the interval number s in the equations as optimal design variables and representing the lower and th e upper bounds of each interval number as the boundary constrain of the variable respectively, the maximum and the minimum of various components of the solution are achieved by using the constrained optimization method

    將方程組中的所有區間數都作為設計變量，區間量的變化區間作為相應的設計變量的邊界約束，運用約束優化法求出方程組解的各元素的最大值和最小值。
