Strategic concepts lie on a spectrum between general problem solving strategies (such as means-ends analysis) and specific domain knowledge (like a Shih-Tzu is a dog.) They contain information about objects and relationships in a domain, but also have processing strategies. These provide a root for innovative problem-solving behavior. This paper deals with the learning of these Generic Teleological Mechanisms (GTMs), which are strategic concepts.[p368]

"GTMs specify complex, abstract patterns of device functions and device behaviors for achieving the functions."

The task: generate a GTM from a single positive and a single negative example of that GTM. These are represented in terms of their Structure, Behaviors, and Functions (SBF).[p369]

Functions are used as indexes into case memory.[p371]

The system works to reduce the difference between the current and desired function. When it fails, an oracle gives a good design for IDeAL to learn from.

Substances are what flow between components.[p374]

The problem solving context determines how the new case is indexed. [p385]
