comment Expressing Sets as Regular Expressions
@blues5938 I think more important than thinking about "accurracy" is to think how prove that a regular expression exactly represent a given set of strings , e.g. your setof strings defined by 1. or your set of string given by 2.

comment Expressing Sets as Regular Expressions
I missed your edit. I think wil match all required string, but I will heck this. But the three other patterns are wrong. If the regular expression is correct, it is unclrear what means "more accurate". You must define some measure for accuracy. One possibility is to count the number of characters in a pattern string and say a pattern is more accurate ithan another pattern if it needs less characters. (10∪0)*(λ∪1)00 has length 14, my pattern (10∪0)(10∪0)*0 hs length 14, too so both have the same accuracy if we use this accuracy metric

I don't know what means 'more' accurate: Either it is accurate or it is not. My regular expressions match exactly that what is required. Your regexp in 1. don't match 100

But maybe this is not availible in your syntax.

Why do you need this? I means 1 can appear at this position. he usual regular epression syntax is 1? for this.
