Hypercomputation Computing Beyond the Church-Turing Barrier

From the reviews:

"During the last two decades hypercomputation has attracted more and more interest within computer science. ... The present book gives an introduction to several such approaches. ... this is the first attempt to collect such material in book form. ... For somebody interested in hypercomputation the book is a good start in order to get an idea about different questions and approaches relevant in that area." (Klaus Meer, Mathematical Reviews, Issue 2009 j)

"To anyone unfamiliar with the notion of hypercomputation picking up this book, it will be an intriguing and informative volume. ... It will be very informative for someone coming from outside, say at graduate or advanced undergraduate, level who wants to find out what all the fuss of hypercomputation is about." (P. D. Welch, Studia Logica, Vol. 96, 2010)
