WebJul 6, 2024 · The goal is to find a derivation of the string, using the production rules of the grammar, or to show that no such derivation exists. This is known as parsing the string. When the string is a computer program or a sentence in a natural language, parsing the string is an essential step in determining its meaning. WebDerivation (parse) tree The tree structure shows the rule that is applied to each nonterminal, without showing the order of rule applications. Each internal node of the tree corresponds to a nonterminal, and the leaves of the derivation tree represent the string of terminals. S a aS B λ b Both derivations on the previous slide correspond
