Glossary

Amorphous computer

A collection of computational particles dispersed irregularly on a surface or throughout a volume, where individual particles have no a priori knowledge of their positions or orientations.

Computational particle

A (possibly faulty) individual device for an amorphous computer. Each particle has modest computing power and a modest amount of memory. The particles are not synchronized, although they are all capable of operating at similar speeds, since they are fabricated by the same process. All particles are programmed identically, although each particle has means for storing local state and for generating random numbers.

Field

A function assigning a value to every particle in an amorphous computer.

Gradient

A basic amorphous computing primitive that estimates the distance from each particle to the nearest particle designated as a source of the gradient.

Definition of the Subject

The goal of amorphous computing is to identify organizational principles and...
