In formal language theory, a context-free grammar is in Greibach normal form (GNF) if the right-hand sides of all production rules start with a terminal symbol, optionally followed by some variables. A non-strict form allows one exception to this format restriction for allowing the empty word (epsilon, ε) to be a member of the described language. The normal form was established by Sheila Greibach and it bears her name. WebGreibach normal form should satisfy the following conditions: 1. Non-terminal should generate a single terminal or a terminal followed by any number of non-terminals. 2.
