Yes... my problems right now are all 3D math problems, and need to get
solved by 3D math first principles.

This is backwards.  We don't condition our implementations to fit abstract
patterns for their own sake!  The abstract pattern is supposed to help me
with my implementation.  For 3D math problems, it does not help.

You're missing the basic point: not everyone's day-to-day programming
problems are "Patterns" in the sense discussed by books like "Design
Patterns."  My day-to-day problems are 3D math problems.  They have
absolutely nothing to do with Patterns.  Really!  I end up thinking things
like "do I need a more abstract container for this thingy?" maybe once every
2 months.  Day-to-day it's computation, correctness of test cases, and
optimization.

I can only reiterate: there are many kinds of design that are *not*
Patterns.

I don't *need* an acyclic graph right now.  When I do need it, I am jolly
well not going to implement a general purpose, bloated,
solve-everyone's-problems kind of acyclic graph.  I'm going to do something
rather domain specific for my game's AI.  Why?  Because we don't have the
computing horsepower to afford the recombinations of general purpose
approaches.  When we do, in 20 years or so, maybe I'll use acyclic graph
patterns to solve some of my problems.
