Class 2: Problems and Finite Automata Spring 2010 University of Virginia David Evans Main Question What problems can a particular type of machine solve? What is a problem ? What is a machine ? What does it mean for a machine to solve a problem ? Problems Defining Problem A problem is defined by: –A description of a set of inputs –A description of a set of outputs and the property an output Definition of Finite Automata A finite automaton (FA) is a simple idealized machine used to recognize patterns within input taken from some character set (or alphabet) C. The job of an FA is to accept or reject an input depending on whether the pattern defined by the FA occurs in the input.

2.1 Introduction Finite automata: a rst model of the notion of e ective procedure. (They also have many other applications). The concept of nite automaton can be derived by examining what Deterministic Finite Automata Bakhadyr Khoussainov Computer Science Department, The University of Auckland, New Zealand bmk@cs.auckland.ac.nz In this lecture we introduce deterministic ﬁnite automata, one of the foundational concepts

Nondeterministic Finite Automata . From DFA to NFA • A DFA has exactly one transition from every state on every symbol in the alphabet. • For example, on the string aa there are three: – From q 0 to q 0 to q 0, rejecting – From q 0 to q 0 to q 1, accepting – From q 0 to q 1, getting stuck on the last a • Our convention for this new kind of machine: a string is in L(M) if there Nondeterministic Finite Automata .
