A heuristic rule is any rule that has been found to work well in practice in a given situation and which can therefore be used as a guide whenever one is faced with a similar situation. A heuristic model is a set of such rules usually expressed in mathematical terms.  1, fiche 2, Anglais, - heuristic%20model

The require-link heuristic is used when an evolving model has a link in a place where a near-miss does not. The model link is concerted to a MUST form.  1, fiche 3, Anglais, - require%2Dlink%20heuristic

A system that uses a collection of primitive concepts in mathematics and discovers concepts, such as prime numbers.  1, fiche 4, Anglais, - AM

Record number: 4, Textual support number: 1 CONT

AM attempts to model learning by discovery. Starting from an initial set of elementary mathematical concepts and a set of heuristic rules, it tries to generate interesting new concepts. Central to its operation is an agenda which schedules tasks on the basis of an heuristic evaluation of their usefulness.  1, fiche 4, Anglais, - AM

Cette approche est clairement guidée par les données observées à l'issue d'expériences. On peut envisager une approche alternative, guidée plutôt par des modèles approximatifs. Le système AM de Lenat, qui recherche des lois qualitatives sur des termes spécifiques à la théorie des nombres, relève de cette approche alternative.  1, fiche 4, Français, - AM

In intelligent computer-assisted instruction(ICAI), recovery from errors takes place as weights are updated in different contexts in which the conflict does not exist. Heuristic selection allows immediate action, and the reinforcement of accumulative weights tends to focus on perceived remediation needs quickly, in keeping with the directive altitude typical of model tracing tutors such as ACTP's.  2, fiche 5, Anglais, - error%20recovery

An heuristic used when something in an evolving model corresponds to a different thing in an example. MUST-BE-A links are routed to the most specific shared class in the classification tree above the model thing and the example thing.  1, fiche 6, Anglais, - climb%2Dtree%20heuristic

An heuristic used when a number or interval in an evolving model corresponds to a number in an example. If the model uses a number, the number is replaced by an interval spanning the model' s number and the example's number. If the model uses an interval, the interval is enlarged to reach the example's number.  1, fiche 7, Anglais, - close%2Dinterval%20heuristic
