WebComputation Theory – p.7/27 Step 2: eliminate ǫ-rules Repeat 1. Eliminate the ǫ rule A −→ ǫ from R where A is not the start symbol; 2. For each occurrence of A on the rhs of a rule, add a new rule to R with that occurrence of A deleted; Examples: (1) replace B −→ uAv by B −→ uAv uv; (2) replace B −→ uAvAw by B −→ uAvAw uvAw aAvw uvw. 3. WebThe class of all recursive languages is often called R, although this name is also used for the class RP. This type of language was not defined in the Chomsky hierarchyof (Chomsky 1959). All recursive languages are also recursively enumerable. All regular, context-freeand context-sensitivelanguages are recursive. Definitions[edit]
