Construction of Large Constant Dimension Codes With a Prescribed Minimum Distance
Axel Kohnert, Sascha Kurz
In this paper we construct constant dimension space codes with prescribed minimum distance. There is an increased interest in space codes since a paper by Koetter and Kschischang w…
Demand forecasting for companies with many branches, low sales numbers per product, and non-recurring orderings
Sascha Kurz, Joerg Rambau
We propose the new Top-Dog-Index to quantify the historic deviation of the supply data of many small branches for a commodity group from sales data. On the one hand, the common par…
Lotsize optimization leading to a -median problem with cardinalities
Constantin Gaul, Sascha Kurz, Joerg Rambau
We consider the problem of approximating the branch and size dependent demand of a fashion discounter with many branches by a distributing process being based on the branch deliver…
Enumeration of integral tetrahedra
Sascha Kurz
We determine the numbers of integral tetrahedra with diameter up to isomorphism for all via computer enumeration. Therefore we give an algorithm that enumerates the…
On the minimum diameter of plane integral point sets
Sascha Kurz, Alfred Wassermann
Since ancient times mathematicians consider geometrical objects with integral side lengths. We consider plane integral point sets , which are sets of points in the…
There are integral heptagons, no three points on a line, no four on a circle
Tobias Kreisel, Sascha Kurz
We give two configurations of seven points in the plane, no three points in a line, no four points on a circle with pairwise integral distances. This answers a famous question of P…
