一元材积方程V=aD^b遗传算法的最优拟合研究

A STUDY ON OPTIMUM FITTING OF ONE－WAY VOLUME EQUATION V＝aD^b BY GENETIC ALGORITHMS

在编制一元材积表时，通常是将Ｖ＝ａＤ~ｂ方程采取对数线性化拟合，此时的参数ａ，ｂ并非最优，文中提出用遗传算法最优拟合Ｖ＝ａＤ~ｂ方程。实例验证表明，遗传算法精确、简单，能更好地提高一元材积表的精度。

When making one－way volume table，the equation V＝aDb is oftenused, by transforming the equation into fitting one－way volume equation. However，it isnot optimum fitting to the untransformed function，i．e ，one－wav volume equation it-self．In this paper，Genetic Algorithms is introduced for determing the values of theparameters of one－wav volume equation，and it is proved to be superior to the usualmethod according to practical verifications.
