Regular grammars consist of a four tuple ( N, Σ, P, S ∈ N) where N is the set of non-terminals, Σ is the set of terminals, S is the start non-terminal and P is the set of productions which tell us how to change the start symbol, step by step, into a string in Σ ∗. P can have its productions drawn from one of two types ...
