Call to action

Despite interesting open research questions, the currently available portfolio of algorithms - particularly from KIT and greeNsort® - is rich enough to provide more sustainable alternatives for older established algorithms. In times of climate crisis it is imperative to reduce the energy and hardware consumption now. Hence we call all maintainers of sorting code, in languages, libraries and software to review their sorting-requirements and replace their algorithms with more sustainable ones. For further guidance turn to and

This call to action is not limited to researchers and software-engineers, we also call all teaching computer scientists to update their didactic materials on algorithms and sorting such as textbooks, MOOCs etc. The power of the greeNsort® methods and insights should be available to future generations of computer scientists without restriction from the outset.
