This book constitutes the refereed proceedings of the 5th International Conference on Unconventional Computation, UC 2006, held in York, UK, in September 2006. The 17 revised full papers presented together with four invited full papers were carefully reviewed and selected for inclusion in the book. All current aspects of unconventional computation are addressed - theory as well as experiments and applications.

This book constitutes the refereed proceedings of the 8th International Conference on Developments in Language Theory, DLT 2004, held in Auckland, New Zealand in December 2004.

The 30 revised full papers presented together with 5 invited papers were carefully reviewed and selected from 47 submissions. The main subjects are formal languages, automata, conventional and unconventional computation theory, and applications of automata theory. Among the topics addressed are grammars and acceptors for strings, graphs, and arrays; efficient text algorithms, combinatorial and algebraic...

This Festschrift volume has been published in honor of Cristian Calude on the occasion of his 60th birthday and contains contributions from invited speakers and regular papers presented at the International Workshop on Theoretical Computer Science, WTCS 2012, held in Auckland, New Zealand, in February 2012.

Cristian Calude has made a significant contribution to research in computer science theory. Along with early work by Chaitin, Ku era, Kurtz, Solovay, and Terwijn his papers published in the mid-1990s jointly with Khoussainov, Hertling, and Wang laid the foundation for the development...
