Euclidean traveling salesman problem

(classic problem)

Definition: Find a path of minimum Euclidean distance between points in a plane which includes each point exactly once and returns to its starting point.

See also traveling salesman, spanning tree.

Note: This can be generalized to higher dimensions, for instance, points in a 3-dimensional space. This problem is a special case of traveling salesman since the cost between points is the planar distance instead of arbitrary weights.
