摘要:
三维欧几里得空间中四个非共线非共面点的加权Fermat-Torricelli问题是:给定四个非共线非共面点A1,A2,A3,A4和对应于每个点Ai的正实数(权)Bi,i = 1,2,3,4,找到第五个点,使得到这四个点的加权距离之和最小。本文给出了三维欧几里得空间中四面体加权Fermat-Torricelli问题的一个解析解。
英文摘要:
The weighted Fermat-Torricelli problem for four non-collinear and non-coplanar points in the three dimensional Euclidean Space states that: Given four non-collinear and non-coplanar points A1, A2, A3, A4 and a positive real number (weight) Bi which correspond to each point Ai, for i = 1,2,3,4, find a fifth point such that the sum of the weighted distances to these four points is minimized. We present an analytical solution for the weighted Fermat-Torricelli problem for tetrahedra in the three dimensional Euclidean Space for the case of two pairs of equal weights.
