Abstract [en]

We study the art gallery problem for opposing halfguards: guards that can either see to their left or to theirright only. We present art gallery theorems, show thatthe problem is NP-hard in monotone polygons, presentapproximation algorithms for spiral and staircase poly-gons, and show that the location of half guards in 2-guardable polygons is not restricted to extensions.
