rewriting system | string rewriting

A substitution system in which rules are used to operate on a string consisting of letters of a certain alphabet. String rewriting systems are also variously known as rewriting systems, reduction systems, or term rewriting systems. String rewriting is a particularly useful technique for generating successive iterations of certain types of fractals, such as the box fractal, Cantor dust, Cantor square fractal, and Sierpiński carpet.
