摘要:通過修改Levenberg-Marquardt (LM)參數(shù),結合信賴域方法給出一種新的求解方程組的LM算法。在局部誤差界條件下,證明了該算法具有局部快速收斂性。數(shù)值實驗結果表明,此算法穩(wěn)定、有效。

中圖分類號:O221.1 文獻標志碼:A

從表1中的數(shù)值實驗結果可以看出,ALLM算法相對穩(wěn)定,對于大部分測試的實驗結果,ALLM算法的計算時間小于AELM算法的計算時間,并且當選取的初始點遠離解集時,算例3在參數(shù)θ=05及δ=2、算例5在參數(shù)θ=05及δ=15,2和算例9在參數(shù)θ=05及δ=1,15,2時,ALLM算法的計算量和計算時間均小于AELM算法。

4 結論

本文結合信賴域方法提出了一種求解非線性方程組的修正的LM算法(ALLM算法),在不必假設雅可比矩陣非奇異的局部誤差界條件下,證明了該算法具有局部快速收斂性。可根據(jù)實際應用的需要,通過改變θ和δ值以優(yōu)化λk的選取,數(shù)值實驗結果表明,ALLM算法穩(wěn)定有效。然而雅可比矩陣的計算量和收斂速度還需繼續(xù)改善,如何節(jié)約雅可比矩陣的計算量和提升收斂速度是今后有待解決的問題。

Abstract: A new modified Levenberg-Marquardt (LM) algorithm for solving systems of equations was presented by modifying Levenberg-Marquardt (LM) parameters and combining trust region method. Under the local error bound condition, it was proved that the algorithm has local fast convergence. Numerical results show that this algorithm is stable and effective.

Keywords: Levenberg-Marquardt algorithm; systems of equations; LM parameter; local fast convergence
