Keywords Fermat point; Fermat tree; Minimal path formula; Cost reduction
Abstract The Fermat point minimally connects three points of ?ABC and resultant tree(=Fermat tree) is shorter than the path lengths connected via the excenter; circumcenter; centroid; orthocenter; and incenter; respectively. Fermat point and Fermat tree have a useful meaning in physical and engineering point of view. Finding Fermat point and Fermat tree can contribute to cost reduction for electric circuits; power transmission/distribution lines; and etc; especially for high cost conductors; e.g.; the superconducting power cable. This paper shows a brief review of a recently published article on Fermat point and presents detailed derivation procedure and application example of the formula by which the length of the Fermat tree can be directly calculated.
