Maximal Two-Guard Walks in Polygons

Research output: Contribution to conferencePaper


Deciding two-guard walkability of an n-sided polygon is a well-solved problem. We study the relatedquestion of how far two guards can reach from a given source vertex, in the (more realistic) case that the polygon is not entirely walkable. There can be O(n) such maximal walks, and we show how to find all of them in O(n log n) time.
