Webb25 feb. 2024 · This gives us the following identity: E = E ( 0) + ∑ x ∈ Σ x ∂ E ∂ x. Remembering that terminal symbols are analogous to variables, this is just the Taylor expansion of the regular expression around 0. But this identity is also an algorithm for the construction of a DFA or NFA state, since E ( 0) is 1 if E is nullable, otherwise 0, and ... WebbWe prove this in the following way. To any automaton we associate a system of equations (the solution should be regular expressions) We solve this system like we solve a linear equation system using Arden’s Lemma At the end we get a regular expression for the language recognised by the automaton.
