Model checking is a powerful approach for the formal verification of software. When applicable, it automatically provides complete proofs of correctness, or explains, via counter-examples, why a system is not correct.This book provides a basic introduction to this new technique. The first part describes in simple terms the theoretical basis of model checking: transition systems as a formal model of systems, temporal logic as a formal language for behavioral properties, and model-checking algorithms. The second part explains how to write rich and structured temporal logic specifications in practice, while the third part surveys some of the major model checkers available.

Model checking is a powerful approach for the formal verification of software. It automatically provides complete proofs of correctness, or explains, via counter-examples, why a system is not correct. Here, the author provides a well written and basic introduction to the new technique. The first part describes in simple terms the theoretical basis of model checking: transition systems as a formal model of systems, temporal logic as a formal language for behavioral properties, and model-checking algorithms. The second part explains how to write rich and structured temporal logic specifications in practice, while the third part surveys some of the major model checkers available.

What is Atlantis? Everyone who ever read Plato's description of Atlantis has to admit that there is not a single word written about a super-civilization. Nothing extraordinary, except the fact that these people shall have lived several thousand years before any accepted culture. The included text-analysis reveals the real content and easily explains that the subject Atlantis is everything else, but a ridiculous fairytale. Plato never planned to be a victim of esoterical fantasies, nor of stuck archeology, that in many cases already disproved itself. Plato's 2.400 year old depiction, that is stuffed with lots of detailed measurements, led the german author to a former island in North-Africa. Incredible satellite-images of this area show undoubtedly manmade structures in today's desert. Apart from the solution what the Tuareg-tribe has to do with Atlantis, where the first settlers of the mediterranian islands came from, 8.000 B.C. and what is written on Crete's Phaistos Disc, this is not yet all. The first manuscript of this book has been written in 2002. Nearly all of the conclusions could be proven right, after the author's private expedition in 2006. And this was the occasion, when the workers of a very near oilcamp told him, that there have been found undefinable graves..... more information on www.expedition-atlantis.com]
