[PDF] From Regular Expression to NFA to DFA
The NFA definitely provides an accepting state for the symbol It is proven (Kleene's Theorem) that RE and FA are equivalent language definition methods In following this progression an NFA is constructed first from a regular expression, then the NFA is reconstructed to a DFA, and finally a Transition Table is built

[PDF] From regular expressions to DFAs using compressed NFAs - CORE
Abstract There are two principal methods for turning regular expressions into NFA's - one due to testing, and NFA-to-DFA conversion by subset construction

Since DFAs are special cases of NFAs, NFAs recognize at least the DFA- recognizable (regular) languages • Nothing else • Theorem: If M is an NFA then L(M) is
