Acknowledgements First of all I would like to thank my advisor Winfried Bruns for his inspiring guidance and support. Our discussions have been very helpful, and I am always enjoying to work with him. I also wish to thank all my colleagues at the Institute for Mathematics. They are providing a very pleasant working atmosphere. Many thanks also to Merle for(More)
In this paper we introduce the version 2.5 of Normaliz , a program for the computation of Hilbert bases of rational cones and the normalizations of affine monoids. It may also be used for solving diophantine linear systems of inequalities, equations and congruences. We present some of the new features of the program, as well as some recent achievements.
The software Normaliz implements algorithms for rational cones and affine monoids. In this note we present recent developments. They include the support for (unbounded) polyhedra and semi-open cones. Furthermore, we report on improved algorithms and parallelization, which allow us to compute significantly larger examples.
