Computing systems are often very hard for most people to approach. To some extent this is because of the inherent difficulty of giving machines the ability to communicate in ways which people find natural: not enough is understood about speech and how it is decoded, about the structure and functions of natural languages, about how the average person thinks about problems and processes. However ...

Biomolecular computers, along with quantum computers, may be a future alternative for traditional, silicon-based computers. Main advantages of biomolecular computers are massive parallel processing of data, expanded capacity of storing information and compatibility with living organisms (first attempts of using biomolecular computers in cancer therapy through blocking of improper genetic inform...

When proving invariance properties of programs one is faced with two problems. The rst problem is related to the necessity of proving tautologies of the considered assertion language, whereas the second manifests in the need of nding suuciently strong invariants. This paper focuses on the second problem and describes techniques for the automatic generation of invariants. The rst set of these te...
