Sounds like you've hit on a good simulation of life: to get innovation,
you must be very tolerant of errors!-)

Hi David
It seems that all you are asking for are the capabilities of
Mathematica or Maple or some other CAS. A quick Google reveals that
there is a CAS written in Python, called SAGE. That might be a good
place to start; but I'll admit that I know nothing about it.

Hi,
Are there any libraries for manipulating algebraic expression trees?
In particular, take an expression tree and simplify it down.
I'm working up the next release of PyGene, the genetic programming and
genetic algorithms library.
Part of PyGene works with trees holding algebraic expressions.
