CONT

BLOCKS is able to provide reasons for its statements in terms the student can understand. In the second half of the dialogue, for instance, when BLOCKS points out the redundancy of the student's block (his "measurement" in SOPHIE'S terminology), it can actually lead him to appreciate why his block could not provide any new information, given his current set of hypotheses. This interactive "entrapment" is typical of the Socratic style adopted for the tutor.

Recherche qui consiste à explorer partiellement l’ensemble de configurations possibles (circuits de graphe) en appliquant sur un circuit aléatoire une transformation génératrice d’un nouveau circuit, en comparant les longueurs des deux circuits afin de retenir le plus court et en répétant cette triple opération jusqu’à ce qu’aucune transformation ne produise de circuit plus court. Elle peut aboutir à des solutions de coût fort supérieur à celui de la solution exacte et être piégée dans un minimum local.
