Contour line construction for a new rectangular facility in an existing layout with rectangular departments
In a recent paper, Savas, Batta and Nagi [14] consider the optimal placement of a finite-sized facility in the presence of arbitrarily-shaped barriers under rectilinear travel. T...

Online point location in planar arrangements and its applications
Recently, Har-Peled [HP99b] presented a new randomized technique for online construction of the zone of a curve in a planar arrangement of arcs. In this paper, we present several ...
