The problem is NP-hard in 2D and there is no PTAS for 3D (unless .). Approximation algorithms are known for 2D, but not for 3D..We present,

We try to achieve this separation using a minimum number of a given set of unit disks. We show that a constant factor approximation to this problem can be found in polynomial time using a gre

Fast theoretical solutions are known, e.g. point location in the Voronoi Diagram of ., or specialized structures such as so-called Delaunay hierarchies. However, practitioners tend to deem these solutions as too complicated or computationally too costly to be actually us

Our construction shows that for .×. games, in the worst case both players may perpetually have mixed strategies

While simple examples illustrate that buyers do get larger utilities when behaving strategically, we show that the benefits can be quite limited: We introduce the concept of . to capture the extent to which utility can be increased by strateg
