GAO GRAPH [2 records]

Record 1 1989-06-23

English

Subject field(s)
  • Artificial Intelligence
CONT

Essentially, the basic mechanism of a GAO graph is that of a production system, with the advantages of the finely grained formalism of production rules. But this production system is interpreted with a goal stack of interspersed AND and OR goals that provide the representation with an explicit control structure. In addition, some notion of scope is afforded by a focus of attention that can be shifted with the generation of subgoals.

Record 2 1989-06-13

English

Subject field(s)
  • Artificial Intelligence
  • Continuing Education
CONT

The mechanism used by Brown and VanLehn for simplifying or distorting a procedure represented as a GAO graph is that of deleting rules : the deletion principle. The absence of one rule causes the interpreter to fire another one instead-usually, but not always, leading to an impasse. If no impasse is reached, the bug generated is a repairless one, and is equivalent to the type generated in models based on syntactic manipulations. If an impasse is reached, the stage is set for a repair.
