Unconventional computing

Abstract

Purpose

The purpose of this paper is to review computational techniques that differ from the familiar “von Neumann” or “Turing” model. The review is prompted by an issue of ERCIM News in which a variety of current projects is reviewed, but attention is also given to earlier computational schemes that were important in the development of cybernetic ideas. The early work was aimed at simulation of biological mechanisms, but accepting neurons as complete entities. The current projects now reviewed fall under two headings, one relating to biology, but differing from the earlier studies in giving attention to internal cellular mechanisms. The other heading is quantum computing, which at first sight seems distinct from the first. Attention is drawn to a paper by Ball in 2011that narrows this apparent gap by indicating important connections between quantum physics and biology.

Design/methodology/approach

The aim is to review developments on the internet, especially those of general cybernetic interest.

Findings

The material from the special issue of ERCIM News refers to ongoing research that offers, in the biological context, new computing paradigms with capacity for adaptation and self‐organisation, and in the quantum context super‐fast computing and security.

Practical implications

In addition to the above, two‐way interaction is claimed to give fresh insight into biological mechanisms.

Originality/value

It is hoped this is a valuable periodic review.
