regular language equivalence

Regular language equivalence refers to two sets of rules (or patterns) that describe how strings of symbols can be validly constructed. When we say these two patterns are equivalent, it means they recognize exactly the same group of strings—no more, no less. In other words, they define the same language, even if their structures or descriptions look different. This concept helps us determine if different system specifications or patterns behave identically, ensuring consistency and correctness across various implementations or representations.
