Illuminating labyrinths

open access: yesDiscrete Applied Mathematics, 2004
A labyrinth is defined as a set of line segments \(L\) with pairwise disjoint relative interiors and their complement \(E^{2}\diagdown \bigcup L\) connected. In the paper the variants of the illumination problem previously considered for disjoint line segments are presented and analogous lower and upper bounds for minimum number of light sources ...
