""" Rewrite Rules
DISCLAIMER: This module is experimental. The interface is subject to change.
A rule is a function that transforms one expression into another
Rule :: Expr -> Expr
A strategy is a function that says how a rule should be applied to a syntax
tree. In general strategies take rules and produce a new rule
Strategy :: [Rules], Other-stuff -> Rule
This allows developers to separate a mathematical transformation from the
algorithmic details of applying that transformation. The goal is to separate
the work of mathematical programming from algorithmic programming.
Submodules
strategies.rl - some fundamental rules
strategies.core - generic non-SymPy specific strategies
strategies.traverse - strategies that traverse a SymPy tree
strategies.tools - some conglomerate strategies that do depend on SymPy
