You seem to be suggesting that when you discover a problem to be solved you 
approach it from mathematical first principles? And what sort of 
mathematical pattern could be useful in implementing a singleton for 
instance (leaving aside the obvious distinction required between none and 
unity)? Or the notion of the decorator, or abstract factory or just about 
any common day to day programming problem? You also appear to think that 
patterns provide some sort of direct solution. Implementation is mostly not 
supplied (esp. in GoF) and you have to implement the pattern in whatever 
language you're working in. The solution that a pattern provides is at the 
design level, probably best illustrated by the UML's class and sequence 
diagrams (amongst others). Or perhaps you have an aversion to acyclic 
graphs as well?
