The paper discusses a nonregular cost function and its optimum criterion, presenting an algorithm of constructing and optimal alphabetic binary tree under this criterion.本文讨论一种非正则的评价函数和它的最优化的一种准则,给出在这种准则下构造按字典次序的最优二元树的一种算法。
In this paper, we presented the problem of multi-criterion fitting to a given family tree and gave a solution formula to the multi-criterion fitting problem of the finite discrete family tree.本文提出了给定谱系树的多准则拟合问题,并对有限的离散型谱系树多准则拟合问题给出了求解公式。
