◆Points On A Sphere
What is the maximum number of points that can be placed on the surface of a
unit sphere, if no two points have a distance (along the surface) smaller
than 1 unit?
Notes:
-Unit sphere has a radius of 1 unit.
-Distances will be measured along the surface of the sphere.
試問最多能在單位球面上放置多少點,使得不存在兩點沿球面的距離小於一單位?
註:
- 單位球是半徑為一單位。
- 距離以沿球面的距離計算。
