CONT

The back-chaining sequence ends when a question is asked or a previously stored result is found.

On peut distinguer deux modes de fonctionnement du moteur d'inférence. Si le moteur raisonne de manière régressive - on dit qu'il fonctionne en chaînage arrière. Il s'assigne un but à atteindre (hypothèse) et recherche la manière d'y parvenir. Sinon, le moteur fonctionne en chaînage avant.

CONT

[Quand] la résolution du problème se fait du problème initial vers les primitives, en passant par une décomposition en sous-problèmes, ce type de résolution est appelé chaînage arrière.

chaînage arrière : terme normalisé par l'ISO/CEI et la CSA.
