Turing-équivalent

Turing-équivalent

Désigne un système strictement Turing-complet, c'est-à-dire, pouvant calculer exactement le même ensemble de fonctions que les machines de Turing (les fonctions calculables), sans plus.

Un système non Turing-equivalent ne semble pas pouvoir exister (voir hypercalcul). En effet, il nécessiterait que l'univers soit lui-même non Turing-équivalent ou que le temps ou l'information soit infiniment compressible.
