From the reviews: "In the tradition of all Festschriften, this volume in tribute to Hermann Maurer collects short contributions on a variety of topics of particular relevance to the honoree. Given the diversity of Maurer's published work, these topics range over many areas, which the editors have organized into sections about algorithms, formal languages and automata, learning, and the practice of informatics. ... Nearly every practitioner of computer science or informatics will find something interesting in this volume." (R. Roos, ACM Computing Reviews, December, 2011)
