   In computer science, an ambiguous grammar is a context-free grammar for which there exists a string that can have more than one leftmost derivation or parse tree. Every non-empty context-free language admits an ambiguous grammar by introducing e.g. a duplicate rule.

   What is the difference between ambiguous and unambiguous grammar?

   • Ambiguous Grammar : A context-free grammar is called ambiguous grammar if there exists more than one derivation tree or parse tree. Example – 2. Unambiguous Grammar : A context-free grammar is called unambiguous grammar if there exists one and only one derivation tree or parse tree. Example – Difference between Ambiguous and Unambiguous Grammar :

   Is G ambiguous?

   • Since there are two parse trees for a single string "a+a*a", the grammar G is ambiguous. Ambiguity in Context-Free Grammars - If a context free grammar G has more than one derivation tree for some string w ? L (G), it is called an ambiguous grammar.

   What is an ambiguous language?

   • A language that only admits ambiguous grammars is called an inherently ambiguous language. Deterministic context-free grammars are always unambiguous, and are an important subclass of unambiguous grammars; there are non-deterministic unambiguous grammars, however.

   How do you know if a grammar is ambiguous?

   • The existence of multiple derivations of the same string does not suffice to indicate that the grammar is ambiguous; only multiple leftmost derivations (or, equivalently, multiple parse trees) indicate ambiguity. For example, the simple grammar is an unambiguous grammar for the language { 0+0, 0+1, 1+0, 1+1 }.

   Oct 1, 2023 · A grammar that allows for two (or more) different parse trees to be built for the same expression is called an ambiguous grammar. Ambiguous grammars should always be avoided because the multiplicity of parse trees they allow prevents us from using parse trees to associate a unique meaning (or value, or semantics) to the expression that they ...

   If a context free grammar G has more than one derivation tree for some string w ∈ L(G), it is called an ambiguous grammar. There exist multiple right-most or left-most derivations for some string generated from that grammar.
