The task is to connect the sites to the labels by non-intersecting rectilinear paths, so-called leaders, with at most one bend.\n  In this paper, we study the Multi-Sided Boundary Labeling problem, with labels lying on at least two sides of the enclosing rectangle. We present a polynomial-time algorithm that computes a crossing-free leader layout if one exists.
