A moving walkway (also denoted as moving sidewalk, travelator, autowalk, pedestrian
conveyor, or skywalk) is a slow moving conveyor that transports standing or walking people …

We study a class of geometric optimization problems closely related to the 2-center problem:
Given a set S of n pairs of points in the plane, for every pair, we want to assign red color to a …

In many cases, the facilities to be located cannot be represented by isolated points, but may
be modeled as dimensional structures. Examples for one-dimensional facilities are straight …

Many applications in data analysis such as regression, projective clustering, or support
vector machines can be modeled as location problems in which the facilities to be located …

We study a class of geometric optimization problems closely related to the 2-center problem:
Given a set S of n pairs of points, assign to each point a color (“red” or “blue”) so that each …

In this paper we study a facility location problem in the plane in which a single point (facility)
and a rapid transit line (highway) are simultaneously located in order to minimize the total …

In this paper we extend the Rectilinear 1-center problem as follows: given a set\(S\) of\(n\)
demand points in the plane, simultaneously locate a facility point\(f\) and a rapid transit line …

In this paper, we take a novel perspective on line planning in public transportation: We
interpret line planning as a game where the passengers are players who aim at minimizing …
