SAELF :Sistema de apoio ao estudo em linguagens formais

Abstract

This work presents the development of an online system, implemented in PHP so that the students of the Computer Engineering course at Unipampa have the possibility to carry out the exercises of the discipline of Formal Languages. In this way, assisting in learning and facilitating the understanding of the contents covered in the classroom and with the purpose of making this discipline more attractive in the eyes of the students of the course. The content of the discipline of formal languages is very technical and difficult to assimilate, in this way the development of the SAELF is extremely important. The system has an option to test regular expressions, the possibility of building deterministic and non-deterministic finite automata and generating words. The academic will be able to build deterministic or non-deterministic finite automata, being able to perform word recognition. In word recognition, there are two options: direct recognition, which indicates only whether the word was recognized or not, and step-by-step recognition, which allows the academic to visualize the analysis of a word for each recognized symbol. During the regular expression test, it will be able to enter a certain expression and perform the recognition or not of a word. In the word generation option, the student must insert the symbols of any alphabet and the number of words he wants to list. The system underwent validation with the students of the Formal Languages subject based on a questionnaire and the use of the system, in addition it was also evaluated by Professor Esdras Lins Bispo Junior of the Federal University of Jatai (UFJ) in Goiás, where it was issued an opinion with its assessment.
