Other types of termschar_term is used when we need to match things like a + or , operator. string_term is used when we need to match a whole string, like a language keyword.Nonterminal symbolsNonterminal symbols (short: nonterms) are essentially all non atomic symbols in the grammar. In...
finite set of symbols String : sequence x 1 ... x n of symbols x i from the alphabet Σ– Special case: empty string ε Language over Σ : the set of strings that can be generated from Σ – Sigma star Σ* : set of all possible strings over the alphabet Σ Σ = {a, b} Σ...
Anyone can model the energy supplies of a finite world as a bucket of sand and a scooper. If the scooper is used to remove the sand from the bucket, it will eventually become empty. If we start with a larger bucket of sand, perhaps the process can be delayed. Or, i...
2.1 Basic notation Events and strings Consider a universe of symbols A also referred to as events, which are the basic elements to represent discrete-event dynamics. All events throughout this paper are considered elements of A. A string s is either a finite sequence of events or the empty ...
