Parallel terraced scan
Encyclopedia
The parallel terraced scan is a multi-agent
based search technique
that is basic to cognitive architecture
s, such as Copycat
, Letter-string, the Examiner, Tabletop, and others. It was developed by John Rehling and Douglas Hofstadter
at the Center for Research on Concepts and Cognition at Indiana University
, Bloomington
.
The parallel terraced scan foots on the concepts of the workspace, coderack, conceptual memory, and temperature. According to Hofstadter the parallel and random
nature of the processing captures aspects of human cognition

Multi-agent system
A multi-agent system is a system composed of multiple interacting intelligent agents. Multi-agent systems can be used to solve problems that are difficult or impossible for an individual agent or a monolithic system to solve...
based search technique
Search algorithm
In computer science, a search algorithm is an algorithm for finding an item with specified properties among a collection of items. The items may be stored individually as records in a database; or may be elements of a search space defined by a mathematical formula or procedure, such as the roots...

Cognitive architecture
A cognitive architecture is a blueprint for intelligent agents. It proposes computational processes that act like certain cognitive systems, most often, like a person, or acts intelligent under some definition. Cognitive architectures form a subset of general agent architectures...
