The image below shows the seven pieces of a TANGRAM game.
There are a lot of possibilities to arrange these pieces.
One example is shown in the second picture. Overlapping of
pieces is not allowed and all pieces must lie flat on the
ground (two dimensional problem).
The distance between the farthest points in this case is
approximately 5.1 units. Your job is now to rearrange the
pieces so that the distance between the farthest points
becomes a minimum.
