Discuss on Competence and Performance of Computational Systems

Computational systems include both naturally occurring computational system ( NOCS ) and artificial computational system (ACS). Computational competence and computational performance are two fundamental notions of them. Computational competence is the primary concept, and computational performance is the secondary one. A set of general ideas that serve to delimit concepts of NOCS are presented here. They refer to material constraints, environmental constraints, developmental constraints, hierarchical constraints, dynamical constraints, etc. By exploring the computational competence and computational performance of brain neural system, the possibility and the challenge to study NOCS are also discussed.
