O CCM: Chemical Casting Model

o What is CCM?

CCM is a model for emergent computation. CCM works only with local information, i.e., each reaction (action) in CCM refers only a few data, and there is no global plan for the computation. CCM is based on a production system, which is similar to chemical reaction systems (rather than conventional production systems used for developing expert systems). Two features of CCM are as follows.

O RACA: Randomized Asynchronous Cellular Automata

o What is RACA?

RACA is a model for complex systems. Conventional cellular automata, which was studied by Wolfram, are synchronous and deterministic. On the contrary, RACA are asynchronous and non-deterministic, or more precisely, they are randomized. RACA and CCM are similar in their stochastic behavior. (Thus, RACA can be regarded as a sub-model of CCM.)

O Logic/Symbolic Vector Processing

o What is This Research?

The aim of this research was to establish methods of vector processing of logic programming languages and/or symbolic vector processing. The main target machines were vector supercomputers, such as Cray X-MP or Hitachi S-820. However, this research also aimed symbolic supercomputing on SIMD parallel processors, such as CM-1.
