In the x y z coordinate system, an ellipsoid has its center at the point ( 0 , 0 , 0 ) , and semi-axes coinciding with the vectors ( 1 , 2 , 3 ) , ( − 5 , − 2 , 3 ) , and ( 6 , − 9 , 4 ) .
A paraboloid has the general shape of the surface z = x 2 + y 2 , but its vertex location and orientation are different. The paraboloid's vertex is at the point ( 3 , 7 , 4 ) , and it opens up in the direction of the vector ( 9 , − 3 , − 8 ) in the same way in which the surface z = x 2 + y 2 opens up in the direction of the positive z axis.
We want to find the minimum distance d ∗ , between a point P = ( x 1 , y 1 , z 1 ) on the ellipsoid and a point Q = ( x 2 , y 2 , z 2 ) on the paraboloid. If the minimum occurs with P ∗ = ( x 1 ∗ , y 1 ∗ , z 1 ∗ ) , and Q ∗ = ( x 2 ∗ , y 2 ∗ , z 2 ∗ ) , then report the value of ⌊ 1 0 0 ( x 1 ∗ + y 1 ∗ + z 1 ∗ + x 2 ∗ + y 2 ∗ + z 2 ∗ + d ∗ ) ⌋ , where ⌊ ⋅ ⌋ is the floor function; for example, ⌊ 7 . 6 ⌋ = 7 .
