| Abstract: | The traditional complement construction for grammars is long and tedious and causes all of the structure of the original grammar to be lost. A new construction method is introduced which produces a complement grammar that is closely related to the original grammar and therefore amenable to further analysis. The method is demonstrated by means of a nontrivial example. Received October 14, 1993 / July 20, 1995 |
