Thomson construction in automata
WebFor my project, I was asked to write a Python program to execute regular expressions on strings using an algorithm known as Thompson's construction. In this, I have to build a non-deterministic finite automaton (NFA) from a regular expression, and can use this to check if the regular expression matches any given string text. WebConstruction of an FA from an RE. We can use Thompson's Construction to find out a Finite Automaton from a Regular Expression. We will reduce the regular expression into smallest regular expressions and converting these to NFA and finally to DFA. Some basic RA expressions are the following −

This NFA can be used to match strings against the regular expression. This … See more The algorithm works recursively by splitting an expression into its constituent subexpressions, from which the NFA will be constructed using a set of rules. More precisely, from a regular expression E, the obtained automaton … See more Two examples are now given, a small informal one with the result, and a bigger with a step by step application of the algorithm.
