Simplify the following regular expression

WebbWe consider the efficient simplification of regular expressions and suggest a quantitative comparison of heuristics for simplifying regular expressions. To this end, we propose a new normal form for regular expressions, which outperforms previous heuristics while still being computable in linear time. This allows us to determine an exact bound ...

WebbLanguage Exponentiation We can define what it means to “exponentiate” a language as follows: L0 = { ε } The set containing just the empty string. Idea: Any string formed by concatenating zero strings together is the empty string. Ln+1 = LLn Idea: Concatenating (n+1) strings together works by concatenating n strings, then concatenating one more. Webb26 feb. 2024 · For example, my textbook says the following RE can be simplified as such (U denotes the Union operation and the alphabet is {0,1}) (0 U ε)1* = 01* U 1* Shouldn't it just be 01* since ε is the empty string? Isn't it basically a concatenation of {0} and 1*? Also, is ε considered a symbol in an alphabet?
