# Integer Programming and Algorithmic Geometry of Numbers - A tutorial

@inproceedings{Eisenbrand2010IntegerPA, title={Integer Programming and Algorithmic Geometry of Numbers - A tutorial}, author={Friedrich Eisenbrand}, booktitle={50 Years of Integer Programming}, year={2010} }

This chapter surveys a selection of results from the interplay of integer programming and the geometry of numbers. Apart from being a survey, the text is also intended as an entry point into the field. I therefore added exercises at the end of each section to invite the reader to delve deeper into the presented material.
