In formal language theory, a noncontracting grammar is in Kuroda normal form if all production rules are of the form: AB → CD or A → BC or A → B or A...

In computer science, a grammar is informally called a recursive grammar if it contains production rules that are recursive, meaning that expanding a non-terminal...
