New book on the Theory of Fuzzy Computation

Εικόνα
I am really happy to announce the publication of my book on the theory of fuzzy computation. The book is available as an eBook and as a hardback. Readers can freely read the preface and the book's table of contents.

On Computation

In an old entry of this blog, I had criticised a blog post who was a review of my book. The author of that review posted a new post entitled Deflating Hypercomputation, where he advertizes his paper The Physical Church–Turing Thesis: Modest or Bold? This paper is a defense of a "modest version of the Physical Church-Turing thesis":
Any function that is physically computable is  Turing computable. The next question is, of course, what is meant by physical computable? Gualtiero Piccinini, that is, the author of this paper, proposes that "if a physical process is a computation, it can be used by a finite observer to obtain the desired values of a function". Now, finite observers are "human beings and any other intelligent beings of similarly bounded capacities". In an explanation of this description, he includes among observers beings that are located in spacetimes that are (currently?) inaccessible to humans (so hypercomputation near a black hole is not a …
