Even experts have less and less of an understanding of the behavior of complex software systems nowadays. Meanwhile, these systems are increasingly involved in our daily lives, whether as intelligent home automation, in autonomous vehicles or in industrial production. Scientists from Saarland University, two Max Planck Institutes and the Dresden University of Technology now want to develop mechanisms in a new Collaborative Research Center to better communicate the behavior of complex software systems not only to experts but also to the general public. The German Research Foundation is funding this major project with eleven million euros over four years.
