A Note on the 2-Colored Rectilinear Crossing Number of Random Point Sets in the Unit Square
Sergio Cabello, Éva Czabarka, Ruy Fabila-Monroy +5
Let be a set of four points chosen independently, uniformly at random from a square. Join every pair of points of with a straight line segment. Color these edges red if the…
Sink Location Problems in Dynamic Flow Grid Networks
Yuya Higashikawa, Ayano Nishii, Junichi Teruyama +1
A dynamic flow network consists of a directed graph, where nodes called sources represent locations of evacuees, and nodes called sinks represent locations of evacuation facilities…
Faster Algorithms for Evacuation Problems in Networks with the Single Sink of Small Degree
Yuya Higashikawa, Naoki Katoh, Junichi Teruyama +1
In this paper, we propose new algorithms for evacuation problems defined on dynamic flow networks. A dynamic flow network is a directed graph in which source nodes are given suppli…
The Two-Squirrel Problem and Its Relatives
Sergey Bereg, Yuya Higashikawa, Naoki Katoh +3
In this paper, we start with a variation of the star cover problem called the Two-Squirrel problem. Given a set of points in the plane, and two sites and , comp…
