patterns for integration



Also, you could look at James Slagle's thesis, also at MIT.  

Ignoring the fact that what you are doing -- having a computer simulate the
behavior that humans might use for these problems -- is often NOT the best
way to write a program.

As a crude analogy, if you were simulating humans doing arithmetic, asking
to show the fingers used for remembering "carries".
