難題,5邊形中心,高手請來?

2010-06-30 10:56 pm
5邊形5隻角A(0,0), B(50,0), C(80,50), D(70,130), E(0,60)
找一點座標,其往所有角之總和為最小

eg (40,48)=280.6
(40,40)=276.6
其中三角形以內心點為最小,但5邊形呢???
更新1:

dist. from ANS.(centre pt.) to A,B,C,D,E (total) is min. valve eg P(40,48)=P to A +P to B+......+P to E=280.6

更新2:

(40,40) wrong HINTS: ANS=(38.XX,XX.XX)
