In formal language theory, many families of languages are defined using grammars or finite acceptors like pushdown automata and Turing machines. For instance, context-sensitive l...
We define Concurrent Turing Machines (CTMs) as Turing machines with Petri nets as finite control. This leads to machines with arbitrary many tape heads, thus subsuming any class ...
The increasing popularity in the late 1970s of affordable, general-purpose, microprocessor-based personal computers in the US, generated a widespread interest around the world in t...
The paper surveys the fundamental principles of evolvable hardware, introduces main problems of the field and briefly describes the most successful applications. Although evolvab...
Van Lambalgen's Theorem plays an important role in algorithmic randomness, especially when studying relative randomness. In this paper we extend van Lambalgen's Theorem ...
