Abstract

Deterministic Finite Automaton (DFA) creation is an essential phase in the lexical analysis segment of a compiler, which is tasked with converting regular expressions or grammars into finite state machines. Although DFA creation is usually effective, it can become computationally demanding and require significant memory for extensive or intricate languages, particularly when facing state explosion during the conversion process. Conventional techniques such as the subset construction algorithm (which is employed to transform Non-deterministic Finite Automata, NFA, into DFA) may result in large, inefficient DFAs that include unnecessary states and transitions. This document introduces a fresh method to enhance DFA construction by applying the Simulated Annealing (SA) algorithm, a stochastic optimization method, to reduce the number of states and transitions, thereby enhancing the performance of the developed DFA. We assess the effectiveness of this method and illustrate how simulated annealing can be applied to strike a balance between exploration and exploitation throughout the state minimization procedure, considerably decreasing the DFA's size and optimizing its efficacy.
