Generalized fairness and context-free languages
The notion of fairness for generalized shuffle operations was introduced in [10]. The n-fairness property requires, roughly speaking, that in any prefix of a word the difference of the numbers of occurrences of two symbols is at most n. Here we give a new simplified proof for the decidability of uni...

| Summary: | The notion of fairness for generalized shuffle operations was introduced in [10]. The n-fairness property requires, roughly speaking, that in any prefix of a word the difference of the numbers of occurrences of two symbols is at most n. Here we give a new simplified proof for the decidability of uniform n-fairness for context-free languages. Also, we show that the more general, linear or logarithmic, fairness notions are decidable. |
