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.
