Models of computation should cover finite-state automata, regular languages (and regular expressions), pushdown automata, context-free languages, formal grammars, Turing machines, the lambda calculus, and undecidability. At the undergraduate level, students should learn at least enough complexity to under...
pushdown automata, languages, grammars, Turing machines, and computability. This provides an excellent prelude to a compilers course, and also gives good coverage of computability. Complexity theory, including NP-completeness, is probably covered, but it is not a central theme of the course. ...
What is Finite Automata in Compiler Design - An automata is an abstract model of digital computers with discrete inputs and outputs. Every automata include a mechanism for reading inputs. It is considered that input is a string over a given alphabet, wri
Pushdown automata – More complicated than finite state machines, these use regions of memory called stacks to store information as part of a model. Linear-bounded automata (LBA) – Similar to a Turing machine, but the data is limited to a portion of input within a finite group of inputs....
What is Chomsky Hierarchy in compiler design - The Chomsky hierarchy is a collection of various formal grammars. With the use of this formal grammar, it can generate some formal languages. They can be defined by multiple types of devices that can identif
