Covering a set of points with a minimum number of turns
Given a finite set of points in Euclidean space, we can ask what is the minimum number of times a piecewise-linear path must change direction in order to pass through all of them. We prove some new upper and lower bounds for a restricted version of this problem in which all motion is orthogonal to the coordinate axes. © Springer-Verlag Berlin Heidelberg 2003.
