Proving Rice

Der Satz von Rice ist ein Ergebnis der Theoretischen Informatik. Benannt wurde der Satz nach Henry Gordon Rice, der ihn 1953 veröffentlichte. Er besagt, dass es unmöglich ist, eine beliebige nicht-triviale Eigenschaft der erzeugten Funktion einer Turing-Maschine (oder eines Algorithmus in einem anderen Berechenbarkeitsmodell) algorithmisch zu entscheiden. Für spezielle Klassen von Algorithmen ist es zwar möglich – auch automatisiert – einzelne Eigen… WebbDirect proofs of Rice’s Theorem Armando B.

A commutative ring R is a ring of weak global dimension at most one if and only if R is an arithmetical semiprime ring.
