Non-Computability of Consciousness
With the great success in simulating many intelligent behaviors using computing devices, there has been an ongoing debate whether all conscious activities are computational processes. In this paper, the answer to this question is shown to be no. A certain phenomenon of consciousness is demonstrated to be fully represented as a computational process using a quantum computer. Based on the computa...
متن کاملUnderflow revisited
Underflow is a floating-point phenomenon. Although the use of gradual underflow as defended in [2] and [4] is now widespread, most numerical analysts may not be aware of the fact that several implementations of the same principle are in existence, leading to different behavior of code on different platforms, mainly with respect to exception signaling. We intend to thoroughly discuss the slight ...
متن کاملComputability and Non-computability Issues in Amorphous Computing
Amorphous computing systems consist of a huge set of tiny simple stationary or mobile processors whose computational, communication and sensory part is reduced to an absolute minimum. In an airborne medium the processors communicate via a short-range radio while in a waterborne medium via molecular communication. In some cases the computational part of the processors can be simplified down to f...
متن کاملNon-Turing Computers and Non-Turing Computability*
Various examples of Malament-Hogarth (hereafter, M-H) spacetimes are given in Hogarth (1992), but the following artificial example from Earman and Norton (1993) is perhaps the simplest. Start with Minkowski spacetime (R4, η) and choose a scalar field Ω on M such that Ω=1 outside a compact set C⊂M and Ω tends rapidly to infinity as a point r∈C is approached. The spacetime (R4-r, Ω2η), depicted i...
