For reasons of efficiency, term rewriting is usually implemented by graph rewriting. In term rewriting, expressions are represented as terms, whereas in graph rewriting1 these are represented as directed graphs. In contrast to the former, the latter representation allows a sharing of common subexpressions. In graph rewriting expressions are evaluated by rule-based graph transformations. Here we will only consider directed acyclic graphs.
